Each to his own, I don't go for the crowd that has to have everything to 400 points, or have chains around their toys, but I understand why, I don't want some careless dork leaning on my fenders with his belt buckle or jacket zipper tearing up the paint or un controled kids touching everything in sight with dirty sticky fingers, a lot of us go to great pains to build something to show to the general public, it would be nice if they showed us some respect, and they can leave there stupid dogs home too.
I have no answer other than to stay guard on what you bring, I've seen the nude or don't touch sticker and I think it brings a little awareness to who ever sees it.
