Will anyone be there?

I'd probably stop by if it weren't for the 1st auto-x for the season for SCCA-Chicago Region :(

I want to go, but I do not have a helmet. I am afraid to buy one online without finding a local store to try one on first.

Did you read the actual flyer?
It says "HELMET: MINIMUM OF SNELL 2000 RATING. We do have club helmets for loan. However, if you can bring one it is best because of limited quantity and sizes."

I'm sure you'll be fine - even if they don't have a huge amount of them, you only really need a few since there's only what, 3-4 cars out on course at the time? Most likely scenario, you'll have to alternate the helmet with another student. This is exactly what was done at the SCCA-CR school this past weekend.

Also, if they have few sizes, this will make it easier to see which one is right for you before you purchase your own.
