Out in rural areas its not so much trouble in metro areas yeah , you can meet some real nuts . Im right with ya as a kid I did this and found some super cool places . I would later find where I had been on a map and would sometimes end up like 5-8 miles away . Found lots of cool stuff , antlers , shells etc . I found an old junkyard or salvage lot from the 1930's had lots of old glass bottles etc . For a while I would sell them and keep the ones I liked . Some of the coolest older people with some amazing stories about the earlier time period that would let you wander around and just enjoyed your company . However nowadays you really need to be careful and get permission unless your are out in the middle of no where .
