From an out-of-towner away team's fan perspective, I was very impressed by Chase Field: everything from the ease to park, to the wonderfully air-conditioned club area with the food courts, to how courteous everyone was to an away fan, it was a great experience!
The seats themselves offer terrific views, and the field is in pristine condition, and its cool to see the roof open up for a night game! Not cool, however, is watching your team lose after Yu Darvish strikes out 14, not cool!
