Whether you have a few or more Spark teammates attend your team meet up, take some pictures and upload them to your team page or blog so others who couldn't come can share in the group event. Post with Spark names not real names, and if you put in local paper , get permission.
For a morning meet up, DH is fixing coffee and hot water for tea. DS is providing Oatmeal packets and fresh fruit to go with it that can be fixed with the "tea water". Also cinnamon shaker.
Go to Church Rummage sales and garage sale for items for games, prizes, and favors for your meet up. I got 50 mini pigs today, I'll put a cute saying on for 5 cents each & 5 blackboards for 25 cents for signs. Etc.
