Pre 9/11 the walk at Peach Bottom would have been on my list. It isn't bad now but not the good old days anymore.
St Lucie was still a short walk in 2004/05 but no idea what it looks like now.
Susquehanna is a crap shoot. You can catch a spot close to the guard shack or you can end up in the overflow lots. That lot became a disaster area after a respectable snow in 07(?).
