for you bmx lovers and general 80s peeps RAD the Movie

You can go to ABA BMX for the full requirements.

However the basic requirements are:
Helmet (your XC lid is fine, if you don't mind the minimal protection)
Pants (shorts with knee pads are generally not allowed)
Long sleeve shirt (some places allow short sleeve with elbow pads)
Frame and stem must have pads (they can be thin and cheesy, but as long as they are 1/4" thick) - some tracks may not require this (edit: for mountain bikes)
Some tracks won't allow quick releases. I've never been to one that minded, but they generally aren't allowed.

Yeah, I didn't mention memberships, but one is required. However, I think one-day memberships are free. But I think it's only good for well...one day. You can't do that more than once...supposedly.
