Portland is a big scooter town. They have some pretty serious characters in that scene. A few friends of mine roll with em.
A typical scooter club party usually involves a loud, fast punk band playing in front of a makeshift dirtbike track in someone's backyard. The combination of rain and spilled beer usually turns this into a mudfight for everyone.
I once watched a guy launch a modded Lambretta off a wooden ramp into a tree. Good times.
This evening.. You could write a movie about it.
