I am paying top dollar for my tickets as long as I'm being respectful to the people around me I can boo the opponent if I feel like it. Its a sporting event he's a "villain" to our team. Where was he when the boos would pour down on old man crawford? (Fuck him by the way) its not a matter of class its about being a fan(atic)
I've heard great things about it.
I recently checked out "The son" by Philipp Meyer. Half way through and I must say its one of the best books I've read.
