I don't disagree. My data set is atypical but it is my local community and it does have a lot of bike commuters. Of 20 employees at my workplace about 4 commute, none of whom are using backpacks or saddle bags to carry clothes. That's pretty typical here. I think some of you live in communities that are more difficult to commute in. Longer trips, more challenging terrain, lots of bad drivers (not that drivers here don't suck but they're very used to cyclists), inclement weather, etc. A "long" commute here is doing a 3-mile ride on flat ground...
