I've finalized plane and hotel reservations for a trip to Denver in April. Finally -- something to look forward to!

True, it's a conference, and I'll be busy most of the time I'm there. But I do arrive early on the first day (when there's no conference) so I have plenty of time to explore the Mile High City. But where to go? A museum? The theater? The possibilities are nearly endless. What a dilemma to have!
