Does anyone know why tickets on a rainout must be stamped or whatever to make them good for the next day? Coworkers of mine won tickets to the race and it was their first time going to a real event and not a street race, and had a good time even though they didnt get to see it all. But said the line was SO long to validate them to use them today, they opted to just go home instead with the weather looking bad for today. (its looking pretty hopeful though at this time, the skies really clearning up) so now if it is clear they cannot attend today.
