We're going. All the rallies we've been to are very worth it. RV's, vendors, entertainment, tours. Meet lots of good people. Rigs are parked very close together with just enough room to put out slides and awnings and park your tow vehicle or toad. OK with us because we spend very little time in the RV at rallies.
Prep: empty black and grey tanks, fill fresh water tank. You said you have electric - generator? They do have pump out service for a fee. You have to sign up for it. You can view the speedway on www.googlemaps.com and select satellite. It's located off US Hwy 19 in Hampton, GA, south of Atlanta. There is a Walmart right up the road if you need anything else.
