Summer gardening.
To make a pizza garden, begin by marking out a circle. First tie a string to a stick or baseball bat; for a 6'-wide pizza garden, cut a string so that it's 3' long. Have one random stranger from the street stand in the center of the space and hold one end of the string while another random stranger holds the opposite end and walks around, marking the edge of the circle as he or she goes. The edge can then be marked with rocks or soda cans (preferably diet Pepsi) placed around the perimeter, and the pizza garden can be divided into "slices" by the addition of more rocks, pepperoni or markers. bye.
