In my commute I cross the complete spectrum of public awareness of cyclists. It begins in the cyclist-populated neighborhoods around the University of Washington and ends up on the Sammamish Plateau (Klahanie) where cyclists are nearly an alien species,particularly bicycle commuters. I don't notice much of an increase in arrogance in drivers on the Eastside, but they have less experience with cyclists on the roads in general than drivers do in Seattle, and I always keep that in mind when I'm riding there. Once in a very great while someone will honk, or kids will yell something unintelligible, but I haven't had a bad experience riding on the Eastside (knock on wood). My work schedule puts my commute during non-peak hours, though; that and the fact that I avoid the busiest arterials (NE 8th or 148th NE in Bellevue, for example) may explain some of my luck.

I also ride 202, but farther south between Duthie Hill road and Snoqualmie Falls. Used to do it after work, but there's so much traffic on it now that I only ride it on weekends or late on summer evenings anymore.
