This is especially great if you have several elderly members attending. And just a few outdoor toys and lots of open space will keep children entertained while the adults talk. An event that goes over well at our annual family reunions is an auction. Folks bring something they no longer want, and we auction these items off. We use the money to pay the rent on the building we use.
Old photographs are a hit, especially with younger family members.
Old movies are also a hit, though harder to set up. Along those lines, a family tree is interesting. A special activity is usually planned for the children. Last year, extra money was used to buy plain, white t-shirts and fabric paints. The kids painted their own commemorative shirts from the reunion.
