Went with the roommate [1] to play laser tag. About a dozen of us showed up, paid our money for unlimited games for several hours and ran around shooting at each other with light.
One game was played lights out. Not completely though, a few strobe lights blinking randomly provided brief glimpses of the arena (it's Laster Storm, so there are plastic barricades separating the two teams) and the red light from the gun gave your position away (even the headset lights were turned off). Very fun if you can do it.
Then dinner afterwards. Then home to read Bucky. [2]
