...reason they need those huge tunnels other than to move large objects in and out (like setting up for devotionals, etc). But other arenas can do those same things somehow.
During basketball games, those tunnels (certainly not BOTH tunnels) aren't necessary.
But like IndyCoug is saying, I'm not sure how you can solve that problem now. There is certainly a way, but it would take some commitment and dedication. No one at BYU cares enough about that.
