Where to start? Casa Bonita is a must-see (NOT!!!!). If you have some time to get out and about, Rocky Mountain National Park is a winner. I'd recommend two breweries in Summit County if you want to get up into the high country for a drinking tour: The Dillon Dam Brewery and the Bakery Brewery, both have excellent brews! It should still be aspen season down low and south of Denver. If time is a problem, Boulder is always a good side trip and the hills above the town should be golden. Breweries: The Dry Dock in Aurora is one of the most decorated small breweries around. Bill Eye, former brewer of the Dry Dock, has opened his own place called Bierstadt (also a mountain but that's another story). And if you get the chance, we can do a bottle exchange, just send me a way to get in contact with you off line.
