I usually was in 102 but I've been all over. 102 was great because it offered fantastic south end action, you could see the crazies in the SStands, and the tunnel went right past you. At least that is the way it was at MH.
The S. Stands are fun but the action is a little harder to see, espcially at the N. End. Best seats I had were at the 20 12 rows up behind the bench. Never been to New Mile High (I refuse to call it Invesco)
