I went to quite a few games at the old dome, it SUCKED! Couldn't hear a thing, felt sterile and that weird baggie in right covering the excess seating was just odd.
Glad its gone, Target Field is a great baseball venue. It feels small and intimate, whereas the the metrodome was cavernous.
One thing that must've carried over or is just part of the franchise is CRANKING the music. It leaves my head spinning from the inundation of loud noise for hours on end after a game. I mostly only attend games at Target Field so I'm not sure if the trend is league wide or localized but the need to fill every possible second with speaker noise at the game has greatly reduced my enjoyment.
