Yes, the more I think about it, the more I can see how huge it could be if given the space. Detroit practically filled a 70,000 person stadium for Bl. Solanus Casey a couple years ago. Fulton Sheen is probably the most high profile person to be beatified in the United States, perhaps ever. I’m sure they could pull in 100,000 attendees if space were not a constraint.
I’m not sure there are any facilities that large in the Diocese of Peoria. There are no pro-sports teams. There are some big universities with football stadiums. The one in Champaign seats 60,000. That would probably be the biggest that I can think of.
