Um...where were we? Oh yeah...why is Bobby's mom such a hard ass on him? Taking the bike away seems a little harsh for almost getting hit by one car, doesn't it? Mr. Jones probably blew the situation out of proportion when he told her what happened while still reeking of self-loathing and alcohol.
But Bobby's got it together! He gets himself a siren that goes WOO-WOO-WOOO!
This is more like the one I remember.
It has multiple siren modes and you can use it as a bike mounted bullhorn.
