I don't know where Pungo is, but if it's in NC, maybe that's where forum member Old Yellow runs his autox schools. I'm pretty sure when I talked to him over a year ago, he mentioned an "old airfield".
I took an EVO school last year. I was pretty disappointed with the instruction. They couldn't beat my time in my car http://www.usa7s.com/aspnetforum/images/emoticons/nonod.gif. I didn't really learn a whole lot there. I haven't let Brian Garfield who runs the DC schools drive Frankn7 yet, but he is a capable driver, and I feel like I can pick up alot from his schools. He can jump in most cars, and drive FAST the first time out... I think he still beats my times in my car by 1.5 seconds in a 45 second course. http://www.usa7s.com/aspnetforum/images/emoticons/cuss.gif
Also, the DC level 1 school does a decent job with basic drills, like the figure 8 drill, which is important when starting out in autox.
