Guys a lot of people couldn't go because they were from neighbouring cities and all flights were cancelled.
Also, the roads were terrible so people showed up late or not at all. The issue obviously isn't that it didn't sell out, because they made a second show to meet the demand, it's that the weather lowered the attendance.
It was kind of cringeworthy to see a half-empty monster pit and half-empty GA
But there rest of the stadium was pretty well packed.
