I gathered some information from a man that walked across America awhile back. The information was concerning my safety. He said the traffic was a problem, at times. He walked facing traffic . He did not listen to music because he wanted to be constantly aware of his surroundings. He tried to make himself easily seen. He alerted the local law enforcement officials as much as he could when he entered their jurisdiction. I will make my safety a high priority.
I also spent time at a local Highway Patrol office in Jasper, Georgia getting ideas.
