Went to a Rockies vs. Cincinnati Reds ball game and despite the game being terrible, the ball park itself is very unique. It's a very modern and open-aired ballpark set in the heart of Denver that showcases not only the players on the field but also the city itself. You can tell as soon as you get to your seats that the constructors paid a lot of attention to maximizing the sight lines, as even those in the nosebleed sections appear to have great views of the field.

Now...to section 204. It was small and cozy, didn't have to battle a bunch of fans in our seating area. If you sit here for day games, you'll be in heaven because you will be in the shade for most of the day. Best of all, we weren't too far from the field, the mezzanine seats all still feel like they're a part of the first level.
I also like that the mezzanine is kind of like a home run porch, reminiscent of the old Tiger Stadium in Detroit. I'm not sure how capable players are of hitting home runs into the mezzanine but I do know that Coors Field is a very home run friendly park which makes it an exciting place to watch a game.
