Cowboy, if you don't already have one, try to pick up a cheap bicycle somewhere. It sounds kind of silly, but it would add at least a couple of miles to the radius that you can reach on foot. It might open up a previously unavailable opportunity for you.
I knew someone who got a job six miles away from where he lived. He used a bicycle to get there everyday for six weeks until he had enough money to
buy a car, which then enabled him to get a better job that was 15 miles from where he lived.
Sometimes Police Departments give away or sell abandoned bikes cheap. I have seen perfectly good bikes in the free columns of the newspapers, and also in the trash.
Just a thought.
