1 wont happen because all of the guns that can be moved are all sitting at the bottom of the triple. If they wanted to go all out now, the guns would already be out and ready to blow tonight. That leaves 2 and 3. It really doesn't matter which one that they do for the people who are looking to go ride. I would say we will know when they will blow as soon as those guns at the bottom of the triple get moved out onto the mountain.
PS. Hopefully they put most of those guns in one of the parks. Fill out every outlet on the water pipe in the park with movable guns. That would be sweet.
