My unwind activities seem to mirror several peoples...
PC games (Some FPS, some RTS, starting to get hooked on iRacing)
Weekends I'll sometimes go out to the gun range
Now that I've got the space, I've gotten into woodworking, built a few shelves so far, a "hobby board" for painting minis for:
Tabletop strategy games (Car Wars, Ogre, BattleTech mostly)
Getting to the movies on the weekends
And this spring / summer going to get back on my bicycle
