So I got a trip coming up to Denver and wanted to know what there is to do there? I'll initially be out in Keystone/Breckenridge for snowboarding however I'll be making my way back to the downtown Denver area for a couple days as well. Never been to Denver so not sure what there is do. Looking for any recommendations of places to visit, places to eat, etc. I'll have a rental car so driving here and there won't be an issue. Any ideas? Thanks.
