Veronica, have you checked with Spontaneous Celebrations? They store a ton of hoops for their circus arts group; perhaps they could take them off your hands, if you haven't already found a taker.
You could also try Freecycle.
Yup, SC is taking them! Thanks
I can take them off your hands. email me at email@example.com and I can give you more info. Thanks!
Hula hoops have found a good home!
