I am a Fort Collinsite but I really don't do any sort of urban. I will say I have heard that EPIC has some rails and what not. There are some spots in Old Town that look like they would work but I have a feeling the policia might frown upon it. You could also try the Fossil Creek park south on Lemay. If I think of anything else I will post it but that's all I have got for now, I'm more of a mountain skier.
