Re: Renton vs Boeing Field: if you are on the left side of the aircraft, and below the first layer of clouds (fat chance, so far this winter), you will probably see both on a southerly approach. You can easily identify Renton because the "airport" next to it is at the southern tip of Lake Washington, and it is a much smaller airport (Renton Municipal instead of Boeing Field). There are a number of large manufacturers in Renton, including Kenilworth trucks, right next to Boeing, so it seems like a huge place from the air.
