I came across a strech of shore today with dozens of old rowing boats in various stages of disrepair. 

I am have a hard time fathoming how places like this come into being. Who decides that this is the perfect spot to bring an old boat and let it rest for all eternity?

Sure, after the fifth boat, the place is probably known, at least locally. The first one may be pure coincidence. 

But the second boat.

Where did that come from?
