I had my first ever experience with a POLITE motorbikes the other day. Every other biker I have ever come across on the trail or on the beach (and I ride on the trail and beach allot, seeing an average of 3 bikes per ride) has ignored as and powered on past. My horse ignores them. However, The other day I was leading my horse up a hill at the end of the ride, when a bike, coming the other way saw us, slowed right down, cut the engine and rolled on past. I smiled and waved, and my horse stared at the bike with giant bug eyes, thinking, 'Why the heck doesn't that bike have an engine?'
Of course, the second they were past they gunned forward and revved off, causing my mare to jump slightly. Turns out she's not used to polite bikers, but hey! At least the rider tried.
