I was at the double tree at sea-tac airport, headed to the penthouse when what do I see a perfect looking lake. It is between the red lion and the double tree. You would never know it was there unless you were in the elevator. No houses on the lake and I did not see any access points. I looked on the map and did not see anything about it. Does anyone know the name? or if it holds fish? It looks like the perfect forgoten lake. A float tube dream???
