Well thanks to all, I say, after finally finding my post and attendant replies-new to this whole thing and something of an idiot, I admit. Ivyland, PA is on the Rand map and, yes, it is just north of Philly. Noticed Wharton State Park and that could fit in with the plan. Looks like it could be sloggy going, and just turn into a dog romp search. Limited time except for eating-what he does best, but what he will get to do least-no pot licking up there I think.
