Specific answers to questions : 1)Yes , you can park on the Causeway ,
but only on the PA side . Ohio will fine you , but they have a legal pull off area near the end of the Ohio side . 2) In addition to walleye, perch and channels , you can expect crappie , bluegill , brown and yellow bullheads [catfish] and the occassional musky . Basically anything that's in the lake can be caught at the Causeway . 3) Crawlers and leeches are great on a floating jighead rig , but don't forget fatheads, chubs and suckers . Naturally you'll need to adjust the size of your jig . Bigger bait , bigger floating jig . Personally I don't use shiners as they are delicate and die quickly when hooked
anywhere . They don't stand up well to being cast either . That's been my experience . I prefer soft bodied floating jigs , specifically Phelps Floaters . I get mine from Cabelas as I can purchase them in quantity , but they're probably available at BASS Pro . If at Pyme , Richters' has them or Poffs' , but I don't think either one has Phelps . They both work equally well . On the other hand , you can get custom colors at Richters' or Poffs' not available at Cabelas' or BASS Pro . It does make a difference how you hook a minnow though . Hook them passing through the top of the minnows' lip down through the bottom lip . This will keep the minnow swimming in a natural position , but if you hook from the bottom lip up and exiting through the top lip , it will cause the minnow to attempt to right itself , thereby giving it more action . Good Luck !
