18th birthday celebration?

I'm completely stumped on what to do for my birthday coming up. I live in a small town where we don't really have any dance clubs, and it is the middle of winter. I was going to get a tattoo, but I've postponed that till when I can actually afford it and still be able to eat...

Does anyone have ideas for something that is different than birthdays from when we were younger, that doesn't involve a lot of money? I'm really looking for something with only one or a few people.
