A championship fight was called off at the last minute over a variety of venue and purse disagreements. The sanctioning body had given a time limit on making the title fight happen. To reorganize and pull things off in the small amount of time left was a long shot. Something fantastical had to happen fast.
Finding a unique angle
It was determined that as long as all the official fight criteria were met, the bout didn't necessarily have to take place in a public arena or stadium. And it wasn't necessary for individuals to pay $s per ticket. If someone wanted to flip the bill for the whole thing, they could technically host the event in their back yard.
