I've seen a picture of you Larry, you look like a serial killer....
Seriously though, I would not trust a person I don't know with my child these days no matter how warm and cuddly they look. Remember, Ted Bundy didn't look the part of a serial killer, but......
I have to be extra watchful with kids around my bike. They seem to be attracted to all the chrome, and I'd hate to see them get burned on the pipes. I've let kids sit on it as long as they are calm, well behaved, and ask please. I'm big on respect, of other people and their property.
