The old Missoula Athletic Club had 2 bubbles at the base of Hellgate Canyon for many, many years that survived. And that is the windiest place in the entire valley.That's kind of what I was thinking. I know msu has a bubble on their campus that students use for intramurals and stuff. Have they had problems with their bubble? NDSU used to have a bubble before their new facility. Did they ever have problems? Perhaps we got a defective product.
