I don't have any pictures handy, but I've found some strange things in the woods over the years. Balloons and golf balls seem to be ubiquitous over the entire continent. Hike hours out into the mountains, miles from the nearest road, and sure as hell there's a golf ball or scrap of mylar... One particular balloon had a note attached, written in Spanish, from a girl to Santa asking for a doll.
Another time a UFO floated overhead, coming lower and lower, and crashing into some trees a mile or so away but still visible from the cabin. Shot a compass bearing and went hiking to the location. The "UFO" was a dozen balloons tied together with all sorts of religious things attached, like a Saint-somebody medallion and a Jesus greeting card with a name and address. I wrote to the address, and received a reply from a lady saying she sent up a similar "balloon rosary" every year. This year it only went about 90 miles...
Hatchet (2 or 3), Case pocketknife, wallet, loggers tape measure, baby's grave (very recent and illegal), hundreds and hundreds of archaeological sites (what I was paid to look for)... I have a small collection of hunting arrows, and enough antlers that I stopped picking up any that were cracked or chewed on (rodents need them for calcium).
