What does this sign mean?

I was fishing a little trout stream last weekend in the Laurel Highlands.  Not far from High Point Lake and I saw this sign, they were everywhere, along with fish permitted signs.  I've never seen one like it before.  Anyone know?  Is it leased hunting club land?
 

Regulated hunting grounds permits - 34 Pa. Cons. Stat. § 2928
§ 2928.  Regulated hunting grounds permits.
        (a)  Eligibility.--Regulated hunting grounds require a
     minimum of 100 acres of land, or land and water combined, on
     which the permittee must release one of the following species of
     domestically produced game birds: namely, ringneck pheasants,
     bobwhite quail or mallard ducks. Any of the listed species and
     chukar partridges may be released only if they are listed on the
     permit application and propagated by the permittee or received
     from a legal source. At least 100 of each species listed on the
     permit shall be released.
        (b)  Classes of permits.--The following shall be the classes
     of permits:
            (1)  Commercial - open to the public for a fee or other
        charge.
            (2)  Noncommercial - used by permittee only or guests
        with no fee or any charge for the use of the area or the
        birds.
        (c)  Marking boundary.--The boundary of the premises covered
     by a permit as a regulated hunting ground shall be marked in
     such manner that any intruder is warned of the purpose of the
     area and that it is unlawful to enter the area without
     permission. The commission shall recommend wording for signs to
     be used for this purpose.
        (d)  Hunting regulations.--Permittees and their guests may
     shoot the birds released by them during the regulated hunting
     grounds season which shall be set each year by the commission
     without regard to the general Statewide season. Persons hunting
     or taking game birds released under authority of the permit on
     regulated hunting grounds are not required to have and display a
     hunting license, as required by this title, but the methods of
     hunting and taking these game birds shall be in compliance with
     provisions of this title.
        (e)  Seasons and bag limits.--All species of game, other than
     those specified, found on the premises covered by the regulated
     hunting grounds permit may be taken on the premises only by
     persons in possession of a valid hunting or furtaker license and
     only in accordance with the general provisions of this title and
     regulations of the commission governing seasons and bag limits.
        (f)  Tagging killed birds.--Before any released bird killed
     under the provisions of a regulated hunting grounds permit is
     consumed on the premises or removed from the premises, the
     permittee shall attach a tag to each bird killed. The tags shall
     be numbered consecutively and supplied by the commission at
     reasonable cost and shall contain such information as the
     commission may require. No game bird killed on a regulated
     hunting ground shall have the right foot removed until a
     regulated hunting ground tag for the current season is attached
     to the bird. The tags shall remain attached to the individual
     birds until prepared for consumption and shall not be used more
     than once.
        (g)  Dog training and trials.--Dogs may be trained or field
     trials may be held at any time of the year upon the premises
     covered by a regulated hunting grounds permit, and retriever
     trials may be conducted thereon. All birds killed shall be
     included in the reported kill. Except during the open season for
     shooting, no game birds shall be killed while training dogs or
     conducting field trials. The special permit required in this
     title shall first be obtained to conduct a retriever trial
     thereon at any other period.
        (h)  Unlawful acts.--It is unlawful to:
            (1)  Remove from or consume on the premises covered by a
        regulated hunting grounds permit pheasants, bobwhite quail or
        mallard ducks killed in accordance with the provisions of
        this section which have not been tagged as required by this
        section.
            (2)  Violate any of the provisions of this chapter
        regarding marking and tagging of birds.
            (3)  Use any methods to hunt for, chase or kill birds on
        a regulated hunting ground which are not specifically
        permitted by this title.
            (4)  Trap any game bird or have any trap set that is
        capable of taking a game bird alive on any regulated hunting
        grounds unless authorized by this title.
            (5)  Hunt for or take any game on a three-day hunting
        license other than permitted by subsection (d).
            (6)  Violate any of the other provisions of this section.
        (i)  Penalty.--A violation of this section is a summary
     offense of the fifth degree. Each bird or animal involved in a
     violation constitutes a separate offense.

At the very least, dont hunt there without asking.

At the very least, dont hunt there without asking.

 
Oh, I have no intention of hunting there.  I was just curious, because the signs were something I'd never seen before.
 
 

Yes D-nymph it is a club of sorts.  Could be a couple of guys with dogs to train, could be a lot of things, but the noncommercial designation tells us that they do not charge persons to hunt there.

"You see "Three Men Out" in the lower left corner.  I guess that'd be the name of the club?"
 
I was guessing the same thing, but I googled that name and searched the permit number on state and PGC website and got nothing.
