Replying to 60 on a skateboard

I was out riding my motorcycle up rist canyon today, when I got to the top, I took the customary stop to stretch and light one up. This car I passed on the way stops next to me and a punker looking kid gets out and proceeds to put on a one piece leather race suit and full face helmet. Some crazy shit was about to go down. He busts out his long board and tells me he can hit 60 mph going down the road. I think bullshit, so I follow him. We take off, and 10 seconds later, I look down at the speedometer as it reads 60. At the bottom, he's like "damn, I usually go faster"
