Do You Know Where This Was Taken?

Ancient legend tells of the mysterious stone shark fin that can be spotted by sharp-eyed locals. Some say it's a monument left over from St. Brendan The Navigator's visit to the New World in the 5th Century. Others say it's the work of a witch who was long feared by the Indians and early settlers. And still others say it's all a bunch of hooey cooked up by some local Patch editor on a Friday afternoon. Whatever this thing may be - and there's a good chance a lot of us have walked right past it - do you know where this is?
