WOW! From NHL to NBA in 3 hours - Verizon center in DC. I never realized they simply covered up the ice!
Verizon Center Transforms
Since their seasons overlap and there’s only one Verizon Center, the Capitals and Wizards have had to learn how to share. When their games are scheduled back to back in one day, about 40 crew members must transform the ice rink into a basketball court or vice versa in just over three hours. It’s a normal day’s work for the crew but it’s quite impressive to watch.
