Great thinking, certainly don't want to be "that guy". Reminds me of a good permission of mine, a mid 1800 house on the edge ofvtow, complete with separate summer kitchen and spring house. I stop in every so often, and not necessarily to detect. They're older and ill ask if they need anything or help with anything, last trip over I dragged a leaky water heater from their basement. The lady of the house absolutely LOVES those little chocolate Timbits from Tim Horton's and I always show up with a small box for her. Soooo....one day, she calls me at work, which I thought was strange but was good to hear from her. She hadn't seen me for a month or so and thought I was done detecting there, plus...she said a "couple of guys" door-knocked asking permission. She asked me what I thought. I said "Carol, you know those little chocolate treats I bring you?"...she says..."uhh yes". I say "well that s*#t will stop!" She cracked up, when she recovered she said "ok, I get the hint"...I asked her to describe the 2 guys but I did not know them or of them. She also said when they exited their car one guy tossed a cigarette butt in her yard, which she was less than thrilled about. I smoke but would NEVER toss a butt down, especially in a prospective permission's yard! They're awesome people and while they say I'd never wear my welcome out, I don't take chances...(the Timbits don't hurt either). Sorry for rambling...it's POURING out, with no sign of letting up...Stay dry! Ddf.
