Kauffman Stadium has got to be the most overrated stadium in all of sports.  I always see it getting this love and I just don't get it.  I've been to a game there and I thought the location was brutal, ingress/egress sucked, the food was HORRIBLE and the stadium was just 'eh' to me.  

GABP is somewhat understated and not 'sexy' which i get but there isn't a bad seat in the house, super easy to get into and out of in an urban setting, has great views, food is A+ and it is affordable (relatively). 

I think Seattle or Dodger Stadium are favorite parks.
