Looking at some options to do with my son next week while his sister is off in band camp. One option is to bike a rail trail and camp. So I'm looking at the greenbrier river trail and wondering if any hammockers haver been on that one. Im wondering if one direction is better than the other, like, some rail trails go mostly downhill in one direction? And the campgrounds...hammock friendly with trees? Anyone ever do this? My other bike option is the New River trail...anyone have experience hanging hammocks at those campgrounds?
