Summer is the best time to let your inner space geek run rampant, but a truly dark night sky is hard luxury to come by -- most of the United States suffers from extravagant light pollution.
Overcome this challenge and head to Cedar Breaks National Monument in Utah. At over 10,000 feet of elevation, it's got a view on a perfectly dark sky and on nine nights this summer, throws a Star Party. You can bring your own telescope (which you could do any night on your own), but they'll take you to Point Supreme Overlook and let you look through their powerful telescopes, accompanied by park staff an astronomy volunteers to answer your questions.
The 2010 Star Party dates are July 8, 10, 12, August 7, 9, 11, September 6, 8, 10 and are free of charge. Be sure to dress warmly!
