"Escape the winter blues and immerse yourself in a tropical paradise of orchids," invites the Web site for the Mesker Park Zoo and Botanic Garden in Evansville.
The escape is abrupt as visitors pass through a heavy wooden door from frigid air into a warm, humid jungle. Rare and beautiful orchids are tucked into spaces between animal exhibits along a walkway winding through the Amazonia enclosure. They're scheduled to be on display until March 8.
