Another thought that came to mind, has there been any carnivals traveling in the area? Sometimes they have some shady characters running the games and rides.
I appreciate your throwing out some of your good thoughts (particularly on a weekend where there are fewer people "on board" to appreciate/respond).
Personally, I haven't considered a carnival. I have, however, wondered from time to time about the nearby campground as a possible source of "shady characters". (Not because I have any knowledge of said campground or about anybody who has ever camped there, but because I have knowledge of a rural campground on a large manmade lake which became a resort area in a different state. The owner of that campground would tell me from time-to-time about government raids/arrests made at the campgrounds. Per him, he learned from various LE officers that campgrounds, all over the U.S., were "hotbeds" for fugitives from justice, etc. MOO
