On the commute home the other night, I followed this father/son duo for the last few miles of Burke Gilman Trail. The kid has his arms splayed out because of his fat jacket (in yellow), and his little bobble-head helmet bounced as they rode down the trail. I caught up with them at the light in Lake Forest Park - they seemed to be enjoying the night ride.
Oh - and they were holding 20mph most of the way - Movin’!

You don’t often see one for sale in the used markets, probably because once you have one you never really want to let it go.
