text: hi, i am planning a push ball carnival for my company. i can't find anyone that can loan/rent. anyone can help   for foot, horseback or automobiles?  you might try the early 1900s, the last reference i can find is in the 1950s.  however, a few rental shops can acquire the temporary loan of a ball that would be suitable for your purposes.  simply describe the size and type of sphere you wish to use, and they can come up with a substitute.  also, athletic supply houses may be able to provide a similar ball, although it is used more as an exercise ball, not a medicine ball.
