I have currently have two houses. One is on the outskirts of a large metro area and the other in a rural area of Upstate NY. If I had to bug out, I would got to the other house.
The journey between the two houses is for the most part on well travelled interstate. With a major event (bugout), the roads would be congested, if not grid locked. Over the last year, I have mapped out various alternative routes on lesser traveled roads. Yes, I highlighted them on paper maps! I even went so far as to try a route or two (with back up GPS at first and then completely via map). A few months ago, I even did it at night. I found these practices to be so worth the effort. I learned a lot.
