Either I live in an unusual place, or have been very lucky, because roadies I see are some of the most friendly and helpful people I've run across. Whether using high-dollar gear or a 25-year old clunker, they always check to see if you need help if you're stopped, and the vast majority wave or at least nod when we pass. Of course there are some Gear Snobs out there, but I seldom come across them.

Other posts have mentioned that some roadies might seem snobby because they are focussed or concentrating...maybe suffering too!
