I love this activity, because the possibilities are so endless. We did this with a friend of Rachel's over and over again. They didn't always get it right, but they ran around a lot! I've left this up in the front yard so we can do it again another day!
This is what ours looked like: Go under the chairs, around the car, jump over the broom. Then run to the little tree and touch it, run under the branches of the big tree, walk over the bridges (I for some reason have boards and bricks under the deck from the previous owners), then run to the finish line! Finally, fall asleep in a chair from sheer exhaustion ;o)
