What are all those pins on people's vests?
 
Those are Ride or Event pins. Every time a Chapter puts on a Poker Run or other special events are held, like a District Rally, usually a ride pin is available, and are sometimes included in the cost of registration. The pins are basically souvenirs that are fun to look back on for the memories each represents. HINT: Lots of pins = an Old Hand that you may want to ask questions of!
