Spring Mountain is an additive substance. Use caution. Stay away. I couldn't. Damn Terry and Monica.... drug dealers. (LOL!)
Terry and monica were the first of our clan to join and then soon after AlohaGT bought in. After being a mooching guest for a couple months after Kelvin joined, we joined as well. Ryan, Lauren (19), and I have been "regulars" now getting out to SM every 3 weeks or so.... and none of us can get enough. It is a really great track, wonderful facilities and great staff and members. A first class operation all of the way. They change up the track configs weekly to keep you on your toes. We recently spent a couple of days on the new track - and boy or boy is it fun!
Dave, to your quite serious question about safety, there's really only a couple of areas on the track where one could get into trouble. There's a config option that substantially mitigates one of them and for the other it may be best just to tell, tell, and re-tell the GT folks that this is an area where you can give up a 1/4 of a second of lap time in favor of caution. Other than that, a mishap typically results in a slide across some very powdery dirt and an embarassingly dirty car!
