where are you gonna be?
Other than visit me, you can visit downtown, go on the lightrail @ union station in denver, go to red rocks amphitheater, go to garden of the gods (great place to just forget around), go to the great sand dunes (HIGHLY reccomend this place- loving amazing.), and glenwood springs (nice hot springs in the mountains, huge pool and spa, great place to relax.)
Colorado's a great place, have fun and be safe
