Cleaning the Conference Center

On Tuesday night, Vickie and I filled an assignment from church to help clean the LDS Conference Center in downtown Salt Lake City, across the street from Temple Square. The building seats 21,000 people, with no interior pillars at all. As you can see from the pictures, it looks something like the Starship Enterprise.
Vickie ended up cleaning brass railings for 2 1/2 hours (our shift was from 9:30 pm to midnight!) I was assigned to vacuum carpets in two of the seating sections on the main floor, using a back-pack vacuum. My best guess is that I vacuumed a swath of carpet approximately 3 feet wide and a mile long! Will we do that ever again? Well, maybe...
