This may be a really stupid question, but I am wondering how exactly a map helps you on the trail. Are there some sort of markers or recognizable landmarks on the trail itself? Would I need a map if I am going to be on the trail for just a week? Also, how easy is it to stay on the trail? Are the trees marked a certain color? And what about camp sites? Is there location somehow indicated (this is for New York) Finally, can I just print a good map somewhere?
