Trust us on this, no worries about locations to photograph from. Road Atlanta may be the most spectator & photographer friendly circuit in North America. As Chris said, debris fencing where one would expect it, and also not in some areas where one would expect it. The turn 6 & 7 complex allows spectators to get ridiculously close to the action without having to shoot through fencing, you are quite literally standing with the marshals.
But as mentioned by Chris & Phil, Road Atlanta is extremely hilly, none of it is flat, and lugging heavy equipment around will be character building. Kirsten & I tend to park in one location for a while, walk around a bit, then pick up anchor and drive to a different portion of the circuit, repeating the process several times, usually ending up by turn 2, 3, & 4, with Lee, Randy, Phil, and the rest of the T-10 gang for the finish.
