The sound, the bay, and the lakes

 Seattle has water bodies on almost all the sides, it's amazing how it can be so surrounded by water.

First there's the Bay, where an ocean or sea enters a land, is surrounded by land on three sides, and that's this region in general. Then there's the "Sound", aka the "Puget Sound" which is when the bay meanders and dances with the land so there's much smaller bays and penninsula etc within a bay, a complex network of land and water. The sound is the most important part of the region. And then there's the freshwater lakes. There's lake Washington, Lake Union, Green Lake, Bitter Lake, and a thousand other lakes in the area, perfect for swimming and having your tiny water craft and freshwater fishing. It's cool, these water bodies define the area. Perfect for folks into water sports.
