Tonight, Friday, October 7th, is the LA Lakers' first home game of the NBA preseason. After their game is over, the crew at LA's Staples Center will have to get the arena ready to host a concert on Saturday. By Monday they'll have to get it into shape as a basketball court again, as the Clippers, their other NBA tenant, have a game--which they play on their own distinct hardwood floor. When the next Friday rolls around, it's time for an LA Kings ice hockey game. How does the arena shape-shift for every new event? Where does the ice go when it's not a hockey rink? How many boards are there in a basketball court? On today's show, Staples Center operations manager Ed Flewelen calls in to explain.Musical thanks this week to Tricky Diesel for their track, "Still Balling."
