We have our family reunion every summer, too, that we also hold at a state park.
We have a large group, at least a couple of hundred. Each family brings a dish, and a gift. The gifts are raffled off, the money collected helps offset the cost of the reunion fees: decorations, the meat that's barbecued, the crafts for the kid's table, the toys the kids receive, etc.
We have 2 people designated to supervise the craft tables, where the children draw, color, and craft with foam cutouts, stickers, pom poms, etc., and right before the gifts are raffled each child gets to select a toy or $5 gift card, from the toddlers all the way to the teens. We try to get as many things from dollar stores or on clearance, my guy got a cool lime green soccer ball last year.
Two or three of the men get there early to cook the meat, women and other men to decorate. Pictures of relatives who've passed are displayed on posters and hung and those in frames are on a table. Streamers and our family crest banner are hung. We have a volleyball "tournament", usually older vs younger, lol. We have footballs, basketballs and irger sports equipment for those who want to play. We don't do chalk art, the park kept our deposit the first and only year we did, it's not allowed. Also no music :( But we use a microphone for announcements. Truthfully, the majority of the adults just want to talk to each other, not do anything, and we're an outgoing group ;)
Has anyone in your family researched your ancestry? I'm researching mine, I found out a couple of years ago my gggggg-grandfather was one of the 11 original founders of the city of Los Angeles. I thought I was the last to know this, come to find out no one knew. Everyone now wants the information and I also plan to make some posters for this years reunion, showing the family tree.
The new thing we're doing this year is a family cookbook, everyone was asked to submit a recipe and the story behind it. I've done them before as a school fundraiser, that's where I got the idea. Each family that wants one pays the cost, no one is making anything off of it.
Hope something here helped!
