Attendance
One of the things that you can not do as a member no matter what is to miss a meeting. Meetings are very important for any gang so that each biker is on the same page about what they are doing and what is going on within the club. They each get a say, very much like an open democracy.
A lot of gangs are not run like a dictatorship and they actually hear the voices of their other members at these meetings. They want everyone to be content and avoid internal problems at all costs. Who knew that bikers were this strict and well-organized? We always thought they were just riding around with no rules at all.
