when I go, I have most of my AutoX specific stuff in a milk crate (numbers, sun block, chalk, tire pressure gauge, snacks, water, helmet liner, sunglasses). I take all my loose stuff out of my car (spare tire, tools, floor mats, etc) and place it next to my car.

All you really need for the first few times is a safe car (be sure you can pass tech - the organizer should publish a list of what they look for) and an open mind. Once you go a few times, you will know what you need.
