The lightning delay is an incredibly stupid rule anyways. People are more likely to get ran over in a parking lot or in a car crash on the way to the game than struck by lightning. C'mon.
If this is the case it should be mandatory that all stadiums upgrade to closed-roof stadiums within 2 years. God forbid it rains or snows. Someone might freeze to death in the stadium if we let a team play during snow, ya know.
The only reason for this rule is profit. I can only imagine how much people spent on beer and hotdogs etc during over an hour intermission.
In fact, to protect fans safety they might as well not let anyone drink beer (might get a DUI after the game or die of liver damage suddenly), eat a hotdog (might have a heart attack from that extra boost of cholesterol), or eat popcorn (might choke accidentally).
