I was thinking today, as I was crossing some rail road tracks, about how those tracks could be useful in an all out bug out situation. If you had to bug out and the roads were not safe or heavily congested, you could always travel by walking along side rail road tracks. If you carry a map that includes rail road tracks on it, and a good compass, you could do some pretty good traveling. Most tracks go north/south, east/west and might be a good solution to getting out of dodge! One could even flee the country if things were insanely bad by this method. Travel north to Canada and so on. It might take a long time but it would be much faster than traveling through unknown wilderness areas, possibly going in circles. With a well supplied back pack/bob you could really cover some ground and "stay on track" at the same time. Curious to your thoughts on this.
