Discovery Scout

About two weeks ago I drove up to Indiana from Florida for Spring Break. Half the time I was thinking "I bet there is a cache there". I would guess that most rest stops have a cache at them. Does anyone know of a page that maybe is dedicated to rest stop caches? We stopped at so many and I bet I was only 400 feet from a lot of caches. We drive through Florida, Georgia, Tennessee, Kentucky, and Indiana. Thanks! Eric my site National Adventure
