There is a beautiful narrow strait just next to our  summer cottage. It used to be a protected fish migration route, so no building and no fishing were allowed. I think the regulations have changed somewhat, but parts of the shoreline remain untouched.

As kids – maybe 14-17 years old – my brother and I would occassionally take the boat there for a swim. The strait is so sheltered from the wind that the water was always several degrees warmer than anywhere else.
