The dome stuck on consecutive nights requiring our guests to pull on the rope:( Jason has suggested that we raise the tires to apply more pressure on the ring. Seems like that might work. Anybody interested in a work group this week or maybe even tomorrow (Sunday). I am hosting yet another private night tonight so we can't do it today. This will require some blocking and a hydraulic jack as well as some large wrenches. I have everything needed but the enthusiastic manpower.
