Uh... We used to hook up our freshly waxed surfboards to the back of my friends 4X truck up in the mountain snow.
He'd drive real fast we'd ride real scared, LOL!Wearing a pair of roller skates you can get a similar effect feeling hanging onto the back of a small motorbike/moped on a swervy road going real fast. It's best for laughter and thrills if the driver slows down real slow while you go by stray dogs though. (Just enough to scare the crap outa' you while the dog attempts to attack you or the tires) then driver speeds up fast while you both laugh hysterically.
Diving off really high cliffs over the ocean during high winds in hopes of actually making your mark to the deep area of water in which to swim...
Innertubing down the Sacramento river during storms.
Climbing onto to the roof of a prominate public building in broad daylight and having a picnic including blaring tunes on your boombox, running when the authorities arrive.
Um... I have another right off hand but it's not age appropriate for these boards.
*Still thinking...
