Guys...if I may....I'm an out-of-towner who enjoyed the livin' hell out of you all and himself as well during your event. It was my first, and hopefully not my last....depending, of course, on when you decide to schedule it. But, there are other factors involved separate from the weather.
Superformance owners have a scheduled event in April, already. As a matter of fact, it's about 100 miles closer to me than the 653 miles I drove to attend your Austin event. In May, Superformance has a scheduled track event at Virginia Int'l Raceway in Danville, VA. Bottom line is that many of us cannot attend two events in the same month...there's more than just the car owners involved here....think of families, children in school, etc. etc.
Personally, I liked coming to Austin in February....that's always one of the worst months in Memphis weatherwise, so it's like a vacation break for me to leave our sh!tty weather to come down to your sh!tty weather!

But, seriously, having the first scheduled event in the new year is something to think about, too.
BTW....Superformance also has a Fall track event, usually in September each year. Double Venom has his event in June.
So, if you're keeping score...April, May, June and September are already taken. February, March, and October are open right now. And October may be taken by Doug Reed's event he's planning. November gets into Thanksgiving, Christmas in December. January's too cold...period. February...well, there's this event in Austin....

March is still open. July and August is, too, but you all know how hot it can get then.
Bottom line....your best bet is February or March. I'd love to continue to plan on coming to your event...too much fun not to! But...don't let my preferences govern your choice....you guys have more at stake than do I....I'll do my best to continue to be there. But...if it comes down to Austin versus a Superformance sponsored social event, or a Superformance sponsored Track event...well, I'm sure you'll understand.
