This "possible crime scene" thing is intersting. It leads me to think another thread :
( So you "found" someone camping soemwhere in the woods )

Generally when you meet other campers/backpackers what happens ?
Do you sometimes assume a possible criminal ? or do you generally invite them over for a campfire chat ?

And what happns if you camp and find out another camper nearby ? Say you didn't see each other when you camped, but next morning you smelled his/her coffee brewing.

Edit:

And suppose you were planning to leave your tent ..etc and go hunting, bird photography or whatever. Would you leave your stuff with this other camper around ?
