Are there good underage dance clubs?

I live in a small town and we used to have a dance club, but it went belly up. Now my friends and I are looking for a new one. Are there any clubs that allow teens in? Anything from Mt. Hood to Portland would be fine. We really just want somewhere to dance and have fun. So again a club that will let teens in, is cool, has dance floor or at lest a place to dance near Portland. Thanks!
