Curious onlookers on the boardwalk

On my commute back from work (train station) I have to go about 1/4 of a mile over a boardwalk. It always makes an incredible racket as the skateboard wheels bang against each plank of wood. The sound is almost like a machine gun with a slow fire rate. People always turn round to have a look. Yesterday afternoon, an oldish woman carrying two shopping bags appeared to freeze and just stare at me as I approached her. I gave her plenty of distance as I passed and she smiled and said an "an electric skateboard????" Yes! I cried, as I whizzed past her.
