I believe you could find a facility in every district capable of doing so, particularly if you go to a two day district event. You would find the local monies available to help offset the costs of renting an arena if it were a two day event.
In turn, this would free up an additional weekend for clubs to host an invitational prior to qualifiers. That is a prime time for most clubs to find their local gyms available to host their own invitational!
