Swimming the Baltic Sea (Gulf of Riga)

Today found us saying farewell to the Squirrel Shack, taking the shortest intercity transport we have ridden so far (2 hrs. 5 min. Tallinn-Parnu, Estonia), greeting the largest breed of dog we have ever met (Irish Wolfhound...60kgs!), and taking a quick dip in the strangely warm, certainly shallow, and mildly salty Baltic Sea, or to be more specific, the Gulf of Riga. (Thank you google maps)
