I typically drive up to CO when I go so I don't have to rent a vehicle, but I'm taking a quick trip up there in the middle of July for a friend's wedding so I'm flying. I'll be there less than 36 hours all told, but I was gonna grab a rental car and go hit Mt. Evans the day I leave. $260 bucks for the tiniest car they have at the airport for 1.5 days is pretty nuts.
