When I was a kid much if the playground was constructed out of old tires. Car tires, truck tires, tractor tires. There was a fortress made of tires right near the entrance of the playground we called TireTown; it had tire bridges connecting the main fortress to two tire outposts. One of the most common ways to play on TireTown was a tag variant called TireTown Tag, which added the stipulation that you were "it" if you touched the ground or otherwise left the bounds of TireTown (including the bridges and outposts). There was also a tower made of stacked tractor tires, small geodesic tire jungle gyms, and other structures.

There were also the swings and slides and stuff, great big tall BurkeBuilt slides that rose like 20 feet in the air and burned your butt on a hot day.

Of course the personal injury and chemical exposure lawyers prevailed. Google Maps satellite imagery of my elementary school reveals that TireTown, the tire tower, other structures, and original steel swings and slides have all been removed. A nice, safe, colorful plastic foam-padded playground occupies a small corner of the area once occupied by my playground. Such is life.
