Cycling seems to have really taken off over the last few years and there seems to be more people on bikes. Average Joe may not yet know about our trademarked Biker Greetings. I always give the nod, wave, smile or hello whenever I see someone.
On the other hand though, there's been times I've been given the Biker Greetings but at the time I was aloof from being winded or fatigued or just enjoying the scenery and failed to reciprocate. It's always an awkward moment.
