Replying to Stuff to do in Denver.

Ever year in October for my birthday my mom takes me and a friend to somewhere. (Don't hate i'm turning 15) I have been going to Salt Lake City. I went to Alta and Guardsman pass for Preseason skiing. I went to Saga and 4frnt. And I went to Snogression. I have been doing this for the past year or so. But now I want to do something new. I want to go Denver. Is there anything like what i had done in Salt Lake City? Jiberish? Level 1?
