Chapter activities/events are conducted primarily for the benefit of H.O.G. chapter members. There are three categories of activities:
(C) Closed Event - An activity for chapter members, and one guest per member. Expect more members than guests.
(M) Member Event - Open only to Nat'l HOG members. Members may not bring guests.
(O) Open Event - An event open to the general public, or an event where the number of guests is expected to be more than chapter members.
