Don't let Evan fool you with the "learn a little bit" thing. He's good at this.
But we do need to add another person or two to our course design and setup team (we lost Tom to club racing this year), so if you are interested this is a great place to start. You have to help set a few up to learn things about safety, flow and visuals. Then we'll let you try one.
I won't be there, but my $.02 on design at that lot is to keep it pretty simple to see and read. I think there is too much opportunity for things to go very wrong if someone gets lost at speed on that site. Besides, 7 runs on a fast 30 second course is more fun than 5 runs on a tedious 45 second course. Right?
