Mickie, last year's race turned into a major mud fest, but it still couldn't compare to what I saw of your experience at DSG. Here's the "aftermath" thread from last year with plento of pics;

The yargo trail system is super sweet & I'd say it's a bit more like Swayback than OM, with amaybe a little Dead Dog climbing thrown in. The camp grounds are very nice and well maintained with excellent bath houses, but you'll probably have to drive a few minutes to the race area. Definately reserve your camp sites. Also, when you arrive on Friday, go straight to the race start area & stake out a spot on the course for your pit with an EZ up tent thing.
Here's some videos;

I've done this race a couple times & always had a blast, even when it rained last year. It's well organized & laid back too. You guys will have a blast!
