Good topic!!!

This same question was addressed in a recent Australian Moutain Biking magazine & it seems we mountain bikers are the friendliest bunch on the road/trail etc. If i can scan the article i shall post it for you.

I always say hello to folks on the trail. I don't care if you're a downhiller hucking or just a normal rider like myself. All the riders (mtn bikers) we hang round with are pretty friendly and make an effort to say howdy!

I always thought it was polite to say hello to anyone whilst jogging, biking, swimming etc

I dress like a moutain biker on my road bike & still try and say hey to anyone that passes me. Then again i act like a mtn biker on my road bike as it's just extra training.
