Bill Mason on Bikers (in the 80's)

 Pg 201 of the book - Confessions of a Jewel Thief (a riveting read) :

Each day at court's end about twenty or so of Nolan's fellow motorcyclists would leave the spectator section of the court and stop at Ray's office across the street to talk and drink beer. I've never smelled such a group. After they left, we would have to open all the doors and run fans to try to get the body odor out, then the three of us would head out to a bar as usual.
