when you bring a small Tv or big Tv for that matter to a race so you dont miss a nascar race or football game!
and i have seen this done weekends in a row... Bring a tv and X-Box to kill time inbetween races!
when you go to a race and spend 80% wrenching on your car, %10 sleeping, 1% on clensing your self and %9 on eating! Thats when you know your beyond addicted...
