Swimming the Liffy

The River Liffey flows through the center of Dublin. As I was walking down the street, and even though the weather outside was pretty nice, I saw these daring people going for a swim.

I like how they have nearly as many rescue swimmers as they do actual people swimming. 

When I mentioned this to a few friends there response was consistent, "No way I'd swim in that." Apparently it's not the cleanest river.
