This is why I suggest checking out local cafes. I don't mean to go there and eat the food, I mean to go there and hang out. Go look at some of the events and stop by for them. See if there are other events at clubs or something. Not every college hangout is a bar.
As Gettysburg is a college town, we have bistros, cafes, and various clubs. There's one on Stratton Street that opened recently that I plan to check out. They have a weekly drum circle.
Also, look into your local arts council. Being an artist doesn't matter, as you can still enjoy the activities. Look into local theater. I've met people at the Gettysburg showing of Pirates of Penzance, and simply because I decided to pick a random seat alone.
Go to local conventions. The local ones are cheaper, as you don't need to include airfare and hotel. Look into
any local interest that's a bit off the wall, as you'll find people there.
Here. Explore your city's visitors site. Don't discount an event simply because of the venue. I'm not a big fan of country music, but I used to go line dancing every weekend when it was held at the American Legion.
QuickEdit:
Doctor Who Party in August. Go there. You have no excuse not to go to it, and don't try to make one. Go there.
