I think I went through 2 or 3 kites a year as a kid. Many were eaten by trees or telephone wires. Sometimes the crossbar would snap after a few too many nose dives into the ground. A kid down the road would get one kite up almost to the end of the roll of string and then tie it to a stick he stuck in the ground. He would then start up a second kite and keep going. I think I remember him having up to 4 flying at once. It was kind of an inverse image of someone fishing with multiple fishing poles.
