By the looks of your competition, it looks like you did real well!
What was the guy next to you racing with, a lawn tractor? He went 19.21 @ 71 mph - blistering to say the least.
Seriously, you did alright. Right about where I was when I started (you probably did even a little better than I did). My first run, I went on the first yellow and spun the heck out of the tires... I think I ran a 15 something. hehehehe
Nice job.
