  • Raffle – The raffle has gotten off to a roaring start thanks to the help of all of the members who sold tickets at the Deer and Turkey Expo and the Mason Gun Show in February. At this point we have sold about $5,000 worth of tickets, which means we have covered all of our expenses and are now making money for your club. Here are some things you can do to help in the raffle effort:
    • Return those tickets, sooner rather than later. A seller’s prize will be given away at the membership meetings at the end of the meeting. You do not need to be present to win, but you do need to have returned your sold ticket stubs and money to be eligible for a seller’s prize. For every $20 in ticket stubs you turn in, you get one chance at the seller’s prize.
      • At the membership meeting held on Monday, 3/9 we awarded our first 2015 raffle seller’s prize. Congratulations to Bob Doane, he won March’s prize of 500 rounds of. 22 LR ammunition.
      • At the membership meeting in April we will be giving away 350 rounds of Federal .22 LR and a Glock water bottle.
      • You too can be entered to win one of our seller’s prizes. You get one chance at every seller’s prize for every $20 of raffle tickets you turn in. You need not be present to win.
      • Join the fun and help support your club.  Sell those tickets and turn in the money.
      • Also, we are actually beginning to run out of tickets. If you have tickets you will not be able to sell please return them to the club so we can sell them.

        Thanks for your help everyone. Good Luck!

The raffle is a big source of funds for your club. Please help support your club so it can keep providing you with quality programs. Thanks!
