Baking cakes and homemade goodies
Have each member make and decorate a cake.(We do this at Halloween) because of the theme. But can be used any time. Have parents/friends/relatives/teachers/firemen/policemen/etc. Make baked goods such as cookies-Bars-Breads-Pies-Brownies,they donate to your cub or boy scouts. Have an auctioneer come and several non bias judges from your community. Let just the members cakes be judges in several categories such as creepiest cake, best themed cake, smallest cake, etc.
Have judges lay the ribbons beside the cakes and then allow public to view and members and parents. Then after the viewing have the cake auctioneer auction each cake and baked goods. It’s a lot of fun,it gives a sense of accomplishment to the participants and it helps the organization with funds. I had my entire community involved and we made over 500.00. Most of all its great fun.
