of years about how many Georgia and Texas fans were in the stadium in South Bend when they played those schools. By some accounts, they almost equaled the ND fans. I remember watching on TV and thinking it was weird how much red there was in the stadium when they played Georgia last year. And this was South Bend, not a neutral site.
Anyway, a BYU-ND game in the West, and especially in Vegas, definitely would not be a home game for ND, IMO.
