Just arrived home from a lovely 9 mile bike ride along the trans Penine trail to Sheffield , I passed a number of other cyclists & every one nodded & said hello , but yet when I'm out running , you don't get zilch ! I wonder why? I look , I smile , I say hello , nine times out of ten nothing . It just makes me think , it can't be that every one is in the zone surely . Anyway just thought I'd share lol .
