I guess you have never had your hand stabbed with a serving fork reaching for the last chicken wing at Golden Corral during a HOG run. I have learned to give those guys a wide berth.
I heard about that...
But back to the topic, Wouldn't they throw back ball bearings and crack their get back whips if you were too close?
You can ride behind any vehicle or group of bikes you want. Just don't try to join their formation. They don't know you and you don't know them. Keep your distance like you would any other vehicle. Even at a stop light. That's all you need to know.
