Well, that was a disappontment.
We found a nice shady spot near the tomato sales tent and sat there explaining to people, when they asked, that we could not give them a sticker but would not attempt to stop them from talking one or two or more from us. Some were a bit slow on the uptake at first, but when the guideline was explained to them they got right into the game and - very politely - snatched stickers from us.
Not quite left and right/hand over fist but enough that after a few hours there were stickers pretty much everywhere we looked.
The line for 'mater sammiches was reported to be long, and our edler statesman claimed he was beseiged with people taking stickers away from him while he waited to get his sammich. (He put Miracle Whip on it - serves him right!)
We had several groups of Hanover deputies stand near us and watch what was going on, but sadly the person on the other end of their cell phone calls could not help them figure out how to do anything about us.
We had a visit from one of the festival muckety-mucks, who on hearing us say we were not handing anything out/away but merely not objecting if someone took some of our property got a sad sort of look and said something to the effcet of "Oh, like last year." The two deputies who came with her and told us she had something to say to us looked like they knew better than to laugh but wanted to anyhow.
Not a lot of folks OCing and not a lot of folks saying they were CCing either. But we had many good conversations about the cops being second responders and how having a gun with you (as opposed to being at home in the safe/sock drawer) really did improve the chances of not becoming a chalk outline. We'll just have to wait and see if anybody changes their thoughts on carrying in case they need it, as opposed to only when they know they will need it.
