It really hurt this event that they put it the weekend after the Wilmington Pro. But I suppose this is better than scheduling it in early March like they used to.
If you're on the fence about it and the cost of a hotel scares you, it is close enough that you could leave St. Louis really really early Saturday morning, get there, late tech/check-in, and get one course walk in on each side (you get 12 runs so course walks aren't THAT critical) and stay one night at the $50 Super 8 and check out Sunday morning. If you don't qualify for the Challenge, you're done by 11am Sunday and back in St. Louis by 3pm. Win-win!
