how about grass clippings or peat moss something to help hold moisture and keep weeds down.
I don't have weeds! Wish I did, so the campers would have something to do.
how about a project like helping a older person clean up their yard or property.
We've done project camps in the past, but that's not something I can change last-minute. They have TONS of activities that they pay to do: high ropes, zip line, climbing tower, low ropes and team building, crafts, Bible study, worship, archery, mini golf, farm, and garden. This age usually does a canoe trip, but the river is still too high. And we have the rifle range, but it's been too wet to get the backhoe to build the byrm, so we can't do that either. :/
Today after lunch they'll be doing indoor activities and napping, because of the heat.
