Last year we did it at Reedy Creek Park which is on the North East side of Charlotte...right around this time of year too.
Thread with all the info from start to finish, so you get an idea of what was involved in planning it:

And yeah, that was me you met when I snatched that D44 for Nick.
I'd be game for another one. We would need to book sooner than the week before this time around, as we almost didn't get a shelter reserved. Last year we were able to score some swag and raffle it off to help cover the cost of renting the shelter, and what we didn't get from that others pitched in out of their pockets. Food was a group effort and easy stuff....hot dogs and burgers, chips, soda..etc.
Just keep in mind July is going to be a busy month for the SEC...Harlan KY for the Crawl the beginning of July, and then Carolina Beach at the end, so i would suggest doing it either late this month, sometime early-mid June, or in August.
BTW I was just out in Dallas a couple of weeks ago. Have a couple of friends out there (one with a lifted XJ). What part do you live in?
