Yep, had some young rapscallions in a fit of buzzed stupor come by once.
"Hey man, you find my lighter, hehe haha?"
Sez I, "Was it that gold cased Harley Commemoritve Zippo with the nice stones on it?" (A usual or similar response to all such queries)
"Uhh, YEAH! Yeah man, you got it?"
"Never saw it."
Yeah sure they always end up tossing some rocks or asphalt chunks or curses at you once they assume they are a safe distance, but safe distance is relative to my desire to respond. Have some fun.
Was detecting next to a golf course in the park and these guys were taking pot shots at me from about 50 yrds. Heard one whiz by way too close. Stepped behind a field sign and had several balls I had picked up, returned them all down the course on the green when they were approaching one of the holes, really upset them. Eh, they got a one finger salute and then they ambled off.
