One thing I learned from childhood: most stuff burns.
Heck, I remember the metal wheel skateboards.
Plus, we would jump anything, with anything.
"The creek with Danny's big wheel? Ok."
"The dumpster with Jeff's 5 speed? Sure."
"11 kids lined up in the street end to end with a tricycle? Ok, but can I use the downhill to get some speed?"
"Troy's Mom's garage with a suzuki RM80? You bet!!"
