I friend that we square dance with collects aloha shirts and has over 200 in his collection. The one he was wearing the other night looks like a normal tiki and flower patterned one-color print until you look at it and realize that intermixed with the flowers are little busses. It is an official Hawaii bus driver aloha shirt. He also has one with bulldozers on it that is worn by the road crews. He wore a western themed one last night to the dance.
