I'm surprised there are that many incidences, GLC. I ride the same type of roads you do and I've found drivers to be really courteous. Of course, I don't have a tri-bike.

Although, a few years ago hubby and I were heading to Haag Lake past your neck of the woods and a truck pulling a trailer of ATVs was a real jerk and almost ran both of us off the road (and this was at 7am...not like there was any other traffic).
