In 2002 I went to speed week as a spectator. We were driving through the pits, found a pit that says "Crew needed". So we stopped, the guy told us he needed someone to take him down, buckle him in, come get him when the run is done, if you do this, steak dinner tonight for us, heck that was icing on the cake! We were already there.
This relationship continues till this day, and infact the car that I run today I purchased from him.
