Yesterday in Mijmegen, The Netherlands during a soccer match a portion of the stadium collapsed underneath the feet of a large group of jumping fans.
Miraculously no one was hurt! Fortunately an old shipping container that happened to be under that portion of the stands prevented the stands from collapsing any more than they already did, poetntially saving lives.
I love a rowdy crowd at a sporting event but sometimes things can get scary. See the second video below for a video of German fans making the entire stands shake. I would nope out of there before you could say, "Nein!"
