Friday I got to see inside the new Cardinal football stadium. I live in Phoenix temporarily and we went as a HVAC shop crew on a tour. It's not open to the public yet. I can bore you with all the latest and greatest of a stadium but usually they are all the same except for one thing... the football field will roll in and out of the stadium within an hour. Most of the time it will be outside. It's real turf in 120 F weather during the summer days. The field is about 3 feet high and it has 70 7hp motors and several guiding ramps. It's just another wild feat in design. We actually went in there to see the air conditioning system as to our career.
