Arena Changeover from Ice to Basketball - True HD

The Staples Center in Los Angeles does this for the Lakers, Clippers, and Kings as well as for concerts and other large events. What I find interesting is not only are you laying or removing flooring but you have to clean the entire place, change ads, and the team stores have to change stock to support which team is playing. There is also about a ten degree temperature difference between basketball and hockey games.

A lot of the major arenas that have both basketball and hockey teams do this. It is too expensive and time consuming to melt the ice every time. They also do this for concerts and other things held at the arena during hockey season.
