This is why you need topo maps because they show everything you might need to get out of town and not use the congested highways. Railroad tracks, power line, gas lines, creeks, streams, rivers, access roads, dirt roads used by forest rangers and other companies. Best yet get a hand held gps with topo maps and paper topo maps. One thing to think about also is if you are on foot railroad tracks are the easiest to follow because of their gradual grade makes travel so much easier. And yes when I used to go off road we would use either the power line or the access roads to them.
