My experience in Columbia was awesome on Thursday. I parked 10 minutes from the stadium, tailgated with Husker and Mizzou fans, and had a great time talking with all of the Mizzou folks in my section.
With the exception of the obvious down pour, it was a lot of fun. And btw, complaining about being drenched is a bit silly. You were drenched whether you had to walk 2 miles or 2 minutes.
Secondly, there was mud everywhere. That's what happens when it rains 6 inches in 6 hours.
You cant fault him for saying his opinion. If he says that he thinks that its the worse, than its the worse to him. Not everyone is going to like your stadium or experience, so you kindof have to swallow your pride and get over it. not everyone is the same. he was sharing what he thought.
