At home with friends and family. I live between the "Tri-Cities" of Bay City, Midland and Saginaw, Michigan. A couple of FLGS around 20-50 minutes away have game nights that I will go to if my retail schedule ever gives me the right night off.
Hearing a few of you talk about Southeast Michigan is tempting me to make the drive.
Vancouver, BC here. We're lucky to have a good number of FLGSs within an hour's drive that support X-Wing. Some friends have also started a group that meets once or twice a month at a local pub to play. We're also very lucky to be near Washington state where there are many thriving X-Wing communities.
Knoxville TN we have 3 stores we play at in Knoxville and the surrounding areas. Long live the Sun Sphere Defense Fleet!
Fresno CA. Crazy Squirrel Games and Hobby Town USA.
Doncaster, UK at my great local gaming centre, The Grid.

Kirkland, WA, USA...just outside Seattle. I play mostly at home and at friends' homes. But at least 2-3 times a month I play at Games & Gizmos in Redmond, WA on X-Wing night (Mondays) and I try not to miss any tournaments there. I'm thinking about going to other shops to play in Seattle and Bellevue to get more games in...need more games in.
Meeples Games, West Seattle.
Haslett, Michigan, USA (Lansing, Michigan area). Mostly play at home (because it is convenient and because I have a large game room with a big table), with occasional forays to several LGS (Evolution Games, AFK Games or Fortress Games)
Porto Alegre, Brazil. Southernmost state. There are a few shops which regularly host gatherings.
Vancouver Island
A2Z Games in Tucson, Arizona.
Wish I could play at home, but the children are too little and the wife too uninterested in gaming. I just need my twin brother to move out West.
PARAKITOR! COME TO ARIZONA! "With our combined [collections], we could rule the galaxy as [brother] and [brother]."
LGS, although I heard many Cons start to have their own little tournament or play area but I tend to miss those events.
VASSAL
Gametraders Hornsby, Sydney, Australia. An excellent place for a game for anyone in the area.
Copenhagen, Denmark, Europe.
Same place as Forensicus! at the Copenhagen X-wing.
Chelmsford Bunker (games club)
Chelmsford, Essex
(yes just up the road (ie 20 miles or so) from Brentwood ... AKA TOWIE land...)
FLGS in Bratislava, Slovakia. Come by if you can find it. 
Most of our tournaments are a mix of people from Austria, Czech Republic and Slovakia (of course) since it's fairly close to both borders.
Edited by PoldaMoncton, NB (Canada), at my FLGS (Comic Hunter) on Mondays and at home or friends' houses sometimes.
Dartmouth, Nova Scotia, Canada.
The War Room (a room of the house whose sole purpose is for table top games).
Pastimes in Niles, IL. League night on Wednesdays can get 15-20 people sometimes.
I live in Lawrence, Kansas. I've TO'd the last few X-Wing tournaments at Hometown Games.
I live in Norwich, Norfolk, UK. I game at Athena Games (my FLGS), at the local university's Games Society, and at home.
I play in Mount Prospect,IL at Game Plus Store. I wish I had friends or somebody that wants to play with me every day of the week (not like now - only Friday nights at Game Plus).
