All you need is kids and the outdoors.
1. Choose three (or more if you like) backyard landmarks, such as a picnic table, a tree, and a large rock.
2. Have each team or individual line up at the same mark.
3. Start the contest. The first player must hop on one foot to the second mark, skip from there to the third mark, and then jump all the way back on two feet to tag the next teammate in line.
The first team whose members have all completed the course wins. (or create your own variation)
