This is something that I have thought about for a while and I believe could work in certain areas of the USA. With this being said, this will not work in all places, but could help especially in areas where there is a lot of trees. Due to my line of work, I look at a lot of aerial imagery, almost daily and see the areas that people may not when looking at a street map. I have heard many people talk about if you have to bug out or when you are traveling to you BOL, stay off the main highways, and use the less traveled road. Well if you live out the in the stick (more than likely that where you BOL will be) than you know that the US highway/state highway and even county road in some places are the main road. There are not many 4 lanes highways or interstates to use in a lot of these places, so people use the other roadways for getting around. Next people talk about using railroads or abandoned railroad, in my area that won’t work either. The closest railroad is about 9 miles away from my location, but something that we do have in this area are a lot of pipelines or powerlines which means pipeline and powerline right-of-ways. As of right now most pipeline and power companies keep these right-of-ways cleared and mowed down for maintenance and viewing from an airplane or helicopter. These right-of-ways are sometimes miles away from any major populated areas or can be used to navigate around those areas. Something else to note would be any water crossings or rough terrain on these right-of-ways would have to be made without the help of a bridge like a road or railroad would provide. If you are traveling over a long distance then using the roadway might be your best bet, but knowing where these are might help you avoid areas that you might not want to go through. This might be something to think about if you have a BOL and are trying to plan your route to during a major event. Another reasons to know where these are at or around your BOL is for possible routes for potential scavengers or others. This is just something that I have not heard a lot of people talking about, but might help someone think outside the box.
