Hi Al,
I response to your question...No...you need only attend the initial meeting to join the club. You will need to show up 1 hour early to complete the paperwork, show your ID, and pay the initiation fee and club dues. After you are accepted as a member, you can use the club facilities at your discretion.
You need not attend every monthly meeting to be a member tho. However, you will miss having a say in club activities and having your voice heard in the voting process that occurs during club meetings.
Come on down to the next member meeting. Meet some of the most dedicated sportsmen in NH. And join a club that welcomes all who have an interest in shooting and fishing sports.
