Fished the DHALO  of First Fork Sinnemahoning the weekend of the 4th, saw 3 other anglers all weekend.  Stream levels great, fish rose till 10AM and from 7 to 9:30PM.  Best flies were isonychia nymphs and duns, and the wife caught her allotment on Big Yellows.  They rose to caddis in the late evening, as usual i didn't catch on till almost dark.  If you have the time, it's like opening day on a private stream.
