People tend to check in during these times:
Register for Friday night broomball leagues at Rockville Ice Arena by visiting DCSocialSports.com. Fall, Winter, and Spring leagues available.
Bundle up it gets cold because of the ice. And bring $1's they've got vending.
Fun fun fun :D
Holiday stick time sells out so get there EARLY!
Very nice locker rooms for changing into hockey gear before a stick-and-shoot or pickup hockey.
