I've thought the same thing, but Centerville used to have races start as early as 5:00 pm with the Championship races in the dark. This past year DI races moved from the middle of the afternoon to 9:00 am which meant staying overnight the night before or leaving at 4:30 in the morning. I've only been to the meet twice. It's certainly not a required part of the season, but I would like to know as soon as possible if it might mean another overnight trip.
I guess that means I need to know if they are going to move the schedule each year, also.
