Partial view of the beach at Lincoln Park. If you click to enlarge you just might be able to see Coleman Pool at the point of the beach, surrounded by a white wall. Coleman Pool is unusual as it is filled with salt water that is pumped from Puget Sound. As children my brother and I would go swimming in the pool during summer, the only time it was open. The salt water was fun to swim in as it is more buoyant than fresh water.
