Aready planning Sturgis 2013?? Yes I am...

So, I'm headed to Sturgis from Denver next year. The Old Lady is gonna fly to the rally...said she doesn't wanna ride bitch for 400+ miles in one shot. I generally ride solo, none of my friends ride any farther than from one bar to the next. So, it's gonna be a solo trip for me, and I'm good with that. But, what I need is some campground recommendations. I don't really need to know which campgrounds are the shadiest, wildest, quietest, etc. I need to know if there is a specific place that may be the annual spot for large groups from the Denver area. I want to make reservations soon. I figure if I can stay at a place where lots of Denver folks stay, then I can meet some folks to stay in touch with. I know that on my last trip to Sturgis, my brother and I met up with about 40-50 other people from Oklahoma that had sort of adopted a spot at the Chip for Okies to meet and party together. I'm new-ish to Colorado, and I have not been to Sturgis since 1997, and back then I wasn't even old enough to drink. I know it's early, but I wanna get in while prices are as low as possible.
