Denver is nearing the end of the month-long 2010 Biennial of the Americas cultural celebration. The city has pulled out all the stops as host of this year's event, including cool events all over town, a wonderful clean-up effort of Civic Center park in the heart of downtown.On the Fourth of July, there was a huge gathering in Civic Center park to listen to the Colorado Symphony Orchestra and watch a truly remarkable light show and fireworks display. Thanks to my wife, our family and friends of ours enjoyed the show from a fantastic vantage point, on 10th floor balcony at the Denver Post building. As with any fireworks shoot, some worked and some didn't. Here's one of my favorites that I fashioned into an e-card that got circulated around to friends and family who weren't able to witness the show for themselves.
