Dayton Schneider, Elliott Hill, Kami Riddle, Julie Ekwall and other children play in the Gillette, Wyo. city pool after it opened for the first day of the 2012 season. Rainy, cold weather delayed the pool's official opening one day, but within an hour after opening, people were swimming, splashing, diving and tanning. "It's really fun here," Julie Ekwall said.
