The Blue Whale The Blue Whale has become one of the most recognizable attractions on old Route 66 in Oklahoma. Hugh Davis built it in the early 1970s as an anniversary gift to his wife Zelta. The Blue Whale and its pond became a favorite stop and swimming hole for both locals and travelers alike. Hugh was an entrepreneur in the grand old tradition of those roadside attraction proprietors of old. Over the years his park became a destination in itself.
