It is a SOA sponsored event. You do have to RSVP. And no, you don't need to bring anything for the cookout. SOA is paying for it

People that attended last year loved it. All you need is a Subaru, co-driver, a camera (phone camera works), full tank of gas (probably have to fill up atleast once), and 4 hours.
