The main places I hung out at as a teen was the arcade at the mall, the Disney Store when it still had classic Disney stuff (which is closed now, and was turned into a men's clothing store), and went to the movies a lot. Nothing else really comes to mind.

The teenagers around here always hung out in the Wal-Mart parking lot. As a matter of fact, I am fairly certain they still do that now. It's extremely sad.
If it's a place like here, Wal-Mart is pretty much the only place open. Things close up early around here, which is why I honestly didn't hang out too much as a teen. I also didn't have a license to drive.
