This is the same line of thinking I've been working on since I found out that I might have to start flying to and from my towboat.
I've been playing the "I spy" game with the intention of paying more attention to the resources that are "just laying around".
My thanks to Susan; your comments about old gardens hadn't really struck me before.
I forgot who had commented on finding "old camps", but there is an old camp on the Arkansas River, just below Lock & Dam 10 that had canned goods, cooking gear, sleeping bags, shoes, etc laying around. The "etc included I.V. tubing and other medically related equipment there. We figured it was a "meth lab" site that was rousted out by the Ark State Drug Task Force. It had a shack there made from tree timbers/trunks, sheets of tin, and tarps.
That also reminded me that it is wise to carry a "trip wire detector" (an old habit of mine) when you're cutting across country in strange, unfamiliar woods. You don't know who is doing what, where, or how those folks are protecting their illicit activities. Many of the "druggies" are using Vietnam type booby-traps like what they saw on the John Wayne movie: "The Green Berets".
