happens all the time, out some of them stick out...
Two kids behind me are talking... I overhear one say "that's a MONOski." Could't think of anything witty so I let it slide.
Guy on the 2-seat lift, good attitude, we B.S.ed a littie bit on the way up... and then he says, "hey, have you ever tried a real snowboard?" I was on the ball that time: "hey, I was just about to ask you the same thing!" Intelligent discussion followed but I don't think I made us a convert.
More recently:
"How come you're wearing two leashes?"
"If that boot breaks loose, I want my foot to stay close to the binding, so my other knee doesn't get twisted up."
That's the only one that bothers me. But technology will advance.
