I know people who have been, and who loved it. It would be over a 12 hour haul one-way for us to get there from home so I'm not sure how worth it would be.
Really not a fan of the big-crowd camping setup (which is what I've been told it is), or general mayhem that accompanies a lot of people and horses, hotshots trying to out-cowboy each other or show off their speed-gaiting horses, etc.
Outside of the camping experience, what is the actual trail riding like?
