I never minded the format for Reedy with Thursday and Friday being controlled practice and qual on Saturday and last qual on Sunday and mains. Only 2 days off work. Just makes a long weekend. But travel for me was about an hour or so drive for that race. For guys who have to fly in or have longer drives, add a day for travel before and after. Now it's a 6 day event and 4 or them would be days off work. The IIC is a great race, but by Sunday, I'm just done. That's so long to be there and for very little track time. Even running 2 classes. I've never even really thought about Snowbirds. It doesn't even sound like fun being there that long and racing literally all day and night.
If you could fit a world class race like Reedy into Friday controlled practice, Saturday 3 rounds of qual, Sunday 1 round of qual and mains, that would be the best for everyone I think.
