I was thinking of taking the wife to stay somewhere in Shanandoa National Park for a few days while I get in a few section hike miles on the AT, hoping to take Amtrak from Jacksonville Fl, but it's getting that short distance from the closest train station to the Park itself that seems to be the rub, since with no credit cards we don't think we can avail ourselves of a rental car and a taxi would probably cost as much as the whole train trip. Any ideas on getting across that last vast expanse? Thanks!
