I quite remember showing up at a house ... with $50 USD; next to return-self to Pacific Beach (S.Diego area) via A POWERED bike! == Freedom!!

And it was; you got that exactly right.
(I almost talked my mater into allowing me to tackle Palomar Mt./the 200" Hale telescope, then largest evah.)
Still unclear if it could have made the grade ... there's probably lots of data re that climb though, and was then. They had to get that mirror delivered. (I then had no idea I'd soon be in a place where the original drawings were on the mech-drawing-class wall. Synchronicity-before-Jung, yet.)

Anyway, a car was out of question for a 14 yo HS Jr. Then. But that experience launched me later, onto a Lambretta--the Work-of-Art model--and n+1 bikes.
