When John's parents and I went on an Argosy cruise of Lake Washington, we got a very unique view of the WA-520 floating bridge. Lake Washington provides a huge psychological barrier between the city-folk of Seattle and the family-folk of The Eastside. That barrier is likely accentuated by the fact that there are only two bridges to get across the ~20-mile lake, and especially 520 (and the approaches to 520) is typically backed up with traffic that people would rather not deal with unless they have to. Personally I enjoy going over the bridges because I can watch the boaters on the water, catch a great view of mountains, and get an overall fresh-breath-of-air feeling because the sky is so open over the lake. The most painful part of the bridge for me is a gas tax of 9.5 cents that was recently passed to pay for a new 520 bridge and improvements to another highway going through Seattle. (Pump prices here have risen above $3 at some places.)
