yes, remember kids... always lock your bicycle.
to my ears people leaving their bicycles unlocked must either live in heaven or have really really old bicycles... or have some community bicycle program.
there was some hippie plan in amsterdam in the 60's called the "white bicycles". it never really took off though and when it was tried again about 10 years ago all bicycles got stolen.
apparently there's such a program in oregon too, so golden child can still leave his bike unlocked i guess.
