The DC area is the worst place I have ever cycled in. Even got harassed in Rock Creek Park on a regular basis.

I never had problems in the several other places that I lived from 1982 to 1996 except the 2 years in DC. Harassment in Hawaii gradually increased from 1996 on. Commercial truck drivers were the worst until their insurance companies threatened the union to pull out of Hawaii in 1998 unless they fixed the driver problem. No problems with commercial truck drivers from 1998 until the last couple of years.

I have ridden the same way since 1982, so the claims that it is the way some cyclists ride is pure BS.
