I think what we have here in Memphis is much tamer than all that CM stuff. Back in 2011 a couple guys started Cycle Memphis, where we meet at the same spot the first Saturday evening of each month, and ride a different route each time, to some different destination each time that always involves food or drink. We usually have 30 to 40 people each month. The anniversary ride last summer we had just over 100 riders, which I thought was huge lol.
What makes this ride cool is it is very social, everybody is quite friendly to one another, and everybody is willing to help out anyone in need along the way. Also there is a definite leader as he is the guy pulling the big speaker behind his bike with music blasting. Riding with music is simply awesome.
We might get one, maybe two cars honk at us on an entire ride. We always stop for red lights, and roll through stop signs only if it is completely clear. If some people make it through a light and it changes, those who made it through will wait up ahead for the rest to catch up.
I have attended every ride since last May, and I've had an absolute blast every single time.
