That's too true.
On one of my caches I used to have a standing invite to any and all cachers stop by my place for a steak and beer after finishing the cache. Now if I don't know them, I don't want them stopping by.
This is my first post on here so I hope I am doing it right and it works:) I am scared to even make contact with cachers in my area as they are strangers and I have geokids. Maybe 10 years ago I would have had no fear, but not these days, quite a sad state of affairs
