I think we are all guilty of make judgements on others because of our experiences with a few that WERE rude or obnoxious, or because our perception of a look or remark was wrong.
Hopefully those that bike will post to that thread and change the minds of those that only run. Or maybe not. Sometimes first impressions are very hard to change.
I personally didn't spend $1000 dollars on my bike I bought a used one and gave it a good home. I spend as little as possible on clothing, I only have a couple pair of shorts and a couple jerseys that I bought on sale, therefore money has nothing to do with my attitude. LOL Just kidding.
I have never seen that kind of attitude around here, but of course I don't bike where runners run or haven't encountered it yet.
