[DECOY]

looking for a county fair project to make with old tractor tires?

Same ones you've probably seen:
Lay it down and grow flowers in the middle.
Hang it from a tree and make a swing.
Throw it on a tarp to keep it from blowing away.

Add obstacle course/play ground to the list of standards.

Or you can use some of these ideas to get you started...
