Can you find Bootes?

To find Bootes, look for the Big Dipper constellation in the north. Follow the arc made by the Dipper's handle until you see a bright star. This is Arcturus, which is located in what would be the waist of Bootes. The rest of the stars in Bootes form the shape of a kite, with dimmer stars beneath the diamond shape of the kite forming his legs.
