I think the reason why I give everyone either a wave or a nod is the same reason why I nod or smile at a lot of the people I work with, whether they're in my department or not. We're all in this together. Scooters, trikes and harleys all run the same risk of becoming hood ornaments on cages. Whether we spent $200 or $20,000 on our rides, we're all out there with our knees in the breeze.
