How about a computer operations room?
Sexual harrasment seminars.
When I had to attend one of these at a company I used to work for (we all had to, not just me, I swear!), the HR rep was greeting people at the door. She said something like “Revtim, glad you could make it!” (like I had a choice). I said “Well, I thought this would be a great place to meet chicks…” She didn’t see the humor.
So then I slapped her ass and said “It’s a joke sweety! This is why women need to just stay home, cook, and collect their man’s semen in their various holes. They can’t figure out what’s going on in the real world!”
OK, I didn’t really take the joke quite that far…
Cockfight. Pit bull fight.
Day care.

Frat parties. All the girls there are either dating fraternity brothers, or are there hoping to hook up with one.

The condom rack at the grocery store. I tried this, spent the night with a bag of ice.
In an article in the National Lampoon called “How to Not Get Laid”, Gilbert Gottfried claimed the three best places to not meet girls are (in order):
- A Star Trek convention;
- Within a one-block radius of a Star Trek convention; and
- Anywhere in the remote vicinity of a Star Trek convention
Banker bars. You know the ones, dark wood, no loud music, preponderance of martini drinkers. People go there to talk about 2 things: the men about work and sports, and the women about work and people they already know. If you don’t already know these women, you are a distraction. Go away.
The Physics and Engineering departments of any major university.
So in case anybody’s really interested in where not to meet women…
Any bar with a lot of tables. If everybody is sitting around in groups there’s not much opportunity to mingle. Room at or by the bar or lots of standing around room is best.
Magic – The Gathering tournaments
Heck, almost any tournaments or meeting involving a game of some sort. There are certainly some exceptions (Bingo, Bridge, etc), but I’ve had awful luck so far.
Jail.
A few years back I went with my best friend and her sister to pick up their brother from a Magic convention that was going on at the university.
Just walking into the auditorium got everyone’s attention. Aside from the occasional mother, we were the only females in that room. The three of us are quite busty, so their eyes never made it past our chests. Being the eye candy of hundreds of greasy mouth-breathers with dirty glasses was an…interesting experience.
Anyway, I guess if you flip it - Magic conventions are a good place to pick up guys - if you’re REALLY having bad luck elsewhere. But they probably wouldn’t know what to do with you.

The proctologist
The first floor of the building where I work - it’s an IT lab and the entire workforce is composed of males, aged 21-35, who seem not to know how to have conversations with any females.
SW gets in lift full of these guys. She is holding three coffees: Hi, could one of you guys please press the button for 5?
Guys: :rabbit caught in headlights look: uh?
Other guys: Erg?
Still other guys to first guys: We need to re-jigg the hardrive to Defcon 4. Heh…heh. Um.
SW presses 5 and spills coffee.
Chess tournaments.
