So you want to a run a major?
I know there is actually a scene for MB in North Carolina from when I lived there one year, and if PWS can drag a few of his people down, we can get MD/VA in on this, and a couple people up from Georgia/Alabama up, it could be a decent sized event (25+).
I have to get my car inspected in North Carolina sometime before August 31st, so I was planning on going down anyway. If you give a months notice, and this isn't within a week of Summer Jam, you can get people.
You need to give people 4-6 weeks if you want to run a a large event. I don't think a July event is going to pull anything, If you want to do the weekend of the 11th in August, it would be much better I think. If you set a date we can start making arrangements.
I am also not opposed to carpooling with a couple people who want to go from my area, given they understand I need to take out some time either that Friday or Saturday to get my car inspected. I drive to visit my parents in NC every few months, and this drive is much shorter than the one to Final Round.
