The short answer is “no”. We welcome your help and assistance whether or not you choose to join. But the members have deliberately decided to keep the cost of membership at a nominal $20 per year. There is value in becoming a member. Members are privy to more information such as minutes of board meetings. Members also receive targeted newsletters. Members also participate in a members’ raffle to receive free concert tickets.
But if what you prefer to contribute is just your time, you are certainly welcome to do so.
