I was digging through some of my old photos and came across this Dave Jacobs gem from 2009.
This was a typical mellow schoolyard session that turned into a makeshift launch ramp party involving Ryan Fudger, Tony Neyer, Francis Delapena and of course, Dave Jacobs. Someone (I think Tony) figured out that the metal electrical cover in the ground could be lifted up, and propped open with a random box to make something launch-able. This is the sorta thing you would fiddle with as a young kid, so it was amusing to watch. Everyone had a go at the bucky takeoff and progressively got better at riding the thing.
This is Dave Jacobs launchin.
