The spectacular site when hundreds of hot air balloons take flight simultaneously should not be missed if you are in Denver August 22 - 28, 2008. Held at Chatfield State Park, the sky becomes filled with the whimiscal colors and spirit of ballooning. Pets are welcome spectators if properly leashed. Visit the website for a schedule of rates and events. As always, please bring appropriate clean up materials and plenty of drinking water for the pup.
