Climbed cliffs
Spelunked
climbed trees
swung off of trees into streams from 20 feet
waded in the Cuyahoga river
chased snakes through swamps
ski jumped from home made jumps
rode street bikes in the forests
crashed every bike I owned
played whip the sled in winter
poured lead into Tiki talismans
fell out of trees
jumped out of trees
built and crashed unmotorized go karts (On Suicide Hill)
And had a wonderful time.
Ick! ...although I've waded in the Olentangy...
