So now the big question...WHO HAS TRIED: Standing on top of your motorcycle while riding?
I was friends with someone who did that all the time (he may have invented it) til he was killed doing it. Sad but I always thought of him has "The guy who rode his bike while standing on the seat" others called him Indian Larry.
When I saw that sign the first thing I thought of was him.
There was a guy who did that here in Southern Maine, but not from here, who killed himself and in the process critically injured two of his adjacent riders.
