There's a big Baptist church around here, in a northern suburb of Atlanta. Probably the largest building in the county. There's room in that thing for thousands. I've been inside of it once - large "concert sized" TV screens, stadium seating. It's nuts.
I'm not much of a religious man, but I've always thought it should be more of a personal experience. A small Catholic church. The sermon/mass shouldn't have an opening act.
That said, rumor has it the preacher at that Baptist church has a Ferarri *collection*.
