You don't want to know what I think it looks like.
Nope! Never seen anything like and I never want to after reading B Squared's comment.
Not me! I don't even want to guess after reading the other two comments.
@ B Squared and Jacob- I had the same thought and wondered about a fixture "designer" and procurement department for the parks and rec that would order these for public beaches. Odd isn't the word and weird is an apt description. @ Lois - Jacob and B Squared think it's out-of-place and may have more than one purpose. Maybe the city/county were trying to save money in these tight economic times.
