Aut cum scuto aut in scuto
Flat track racing. Did that for 20yrs, likely why I can't hardly get out of bed some mornings.
I did that, on pavement, a few times. Now I limit it to dirt.
Back in the late 70s I saw R. Mamolla break his collar bone at Laguna Seca (or maybe it was Sears Point.)
Maybe better than hitting a deer at 60 mph on a motorcycle. Ask me how I know.
