A passing roadie has never said to me "Thanks, Sweetheart." Percentage wise, I think mtnbikers talk to others more, but I've had more vocally rude encounters with mtnbikers because I think singletrack just creates more obstacles. The few that think it is appropriate to race multi-purpose singletrack on non-race days and tell you to get the F off their trail because it is a race course . . . well, I didn't axe them to be reasonable. It wasn't worth my time. Just don't axe about the bodies at the bottom of the ravine, OK?
