Nice!
I used to walk up there on my SEA layovers just to watch them come and go. The turbine ones were cool but I just love the sound of a radial.
SEA was always one of my favorite layovers but I haven't been there in years. I would also take a bus over the bridge to the Freemont area, to a really nice acoustic guitar store called Dusty Strings, they let me play with their toys, which was fun, and right across the street there was a very good pub called, The Red Door (if I remember correctly). Is that place still there? It's where I had my first Red Hook brew.
