Looks tropical, doesn't it? But it's the saline pool at the Pillar and Post Spa in Ontario, near Niagra on the Lake. The Dudettes sacrificed their fingers for research and and submitted to manicures and hand massages while listening to the soothing sounds of sheets of water coursing down glass sculptures on the wall. Canadians seem to have the spa gene, both in loving to go to them and being gifted in running them.
