I wonder who the anti-Webcor/AltoVelo posters are comparing us to? Road cyclists in general or other racing clubs? How often are the riders on SJBC, LGBRC, MVV, LeVillage, or PenVelo exchanging pleasantries with you as you/they pass?
I generally say "On your left" or something to folks I pass on the road. But I can tell you that there aren't a lot of times other riders will say a darn thing if they pass you. So, it's a two-way street. folks. If you go out for an easy ride in your kit, everyone thinks it's a race.
