So, I was riding up to take my vest to have my AWESOME new clinic patch sewed on professionally. Riding towards me was a guy on what was clearly a white bike (and I say that because he's far enough away at this point it's all that I can tell). He proceeds to stick his left arm straight up into the air. As we get closer, I notice his index finger is extended and pointing in my direction (I was releived that he wasn't telling me that he was #1 in the traditional fashion) . So startled I waved back, and immediately proceeded to take inventory of my surroundings. All was well, and I proceeded to LMAO. He may have just been extremely delighted with the weather here in Houston (as I was), which was in the high 60's yesterday morning. BTW, he did appear to be riding a *. Anyone else seen this unique wave?
