Awesome... nice to see the list growing. We've got some bigger events coming soon that I'll send messages out for, however I know that they're out of town and I don't know how much interest would be shown for them.
I would push the Road America Event, that is going to be huge as well as the Mid-Ohio Grand-Am events with The Mazda Speed Zone, presented by Castrol. I would hit up the entire Great Lakes Region.
