I've got a few more days than you do. It helps that I am working right up to the departure date.
Also I must commend you on you secrecy, I wouldn't be able to keep a secret this big.
Both DVCZerfs and I will be there next week too. We're headed out next Friday, spending the night in Kingsland GA, then headed in on Saturday morning. I'll PM you my number and maybe we can run into each other somewhere along the way.
