This will be my first time hiking the AT. My wife and I are planing on bringing our dog along. She is a little bit crazy on the initial letting go on trails(other trails we do around home) but pretty quickly stays close by us. Obviously you cross roads on the trail and the two day hike we are going to do it looks like we will cross about 10 roads. How do you know the road is coming or do you just not know? I guess I worry about a rabbit or something that she will take an initial run at but she quickly stops. I would not call it chasing even but its just the initial reaction she has. The roads are just something that worries me. Any help would be appreciated. We are going from Pen Mar to Caledonia on the Maryland Pa line.
