You can pretty much give up on spectators showing up for regular bracket events. I love bracket racing but watching it is painful most of the time. Furthermore, it's too confusing for the general populous. I was down there for the big event July 1/2 and had my parents meet me for a visit and to watch me race. This is probably their 4th or 5th bracket event they've seen, and my wife still spent a bunch of time trying to explain what was going on, why the car that crossed the finish line first lost, etc. As far as watching the racing, the fast cars are quite an experience to see, and since we were pitted close to the finish line, we got the full effect. That was worth watching, and I often wonder why there aren't any stands for the spectators at the finish line.
I think the real trick to get more competitors at the track is to find car guys with money and take them down the track. It won't hook everyone, but I think some will be drawn to it. Get them in a fast car that launches hard, and you'll find a few more.
