think how intensely crowded it gets in the base area and on lower showcase on the weekends, especially in Jan/Feb. Then, throw in a reasonably sized event with a bunch of people trying to run it and compete in it. Add lunch time, some ski school busses, some people that don't give a damn about rails, and all this other shit, and you got quite the mess. Fridays may be inconvenient for some to attend, but having a base area event during the day on a weekend is probably going to inconvenience more than it would otherwise.
Just a supposition.
At least it got bumped to next week. A foot of rain sucks ass, and now I don't have to burn for missing some bs studio.
