The Colon Club has one to rent, it is pricey, depending on where in the, because of shipping, it can be upwards of $10,000 to get her to an event. here is the link:http://www.colonclub.com/the-colossal-colon/
I have seen another one in the Northwest are, Belle AKA NWGirl, I think Anita used it recently. I wonder where that one is from and the cost?! I also heard that maybe CCA has one too.
The problem is these traveling "Colons" are BIG and HEAVY and costing to ship around. But I do know there are several out there now.
Good luck and let us know what you find out!!
