only "sport" where the average fan can get a pit pass and be in the "locker room" (garage) 20 minutes before the start of a race. and actually this probably is much cheaper than a box seat or ground level seat on the 50 yd line at a football game.
drivers actually sit at their merchandise trailers to sign merchandise. my old step dad easilly got me rusty wallaces autograph at phoenix last year on a hat. sure you have to wait in line but if youre a brian vickers fan there were only about 9 people at his trailer
(this was shortly after he wrecked JJ at talledega)
jr. gordon, and JJ easilly had the most people waiting in line, and all 3 quickly ran out of all merchandise...
