With what can be described as a golden ticket (for the duck blind), you'll get unlimited beer and food. The only downside? You have to sit through a whole collegiate baseball game.
But seriously, it's a great time. It's first come first serve, so if you want good seats right against the field, get there when the gates first open. You can kill the time with the unlimited beer and food you have access to.
Going to a Mallard's game is a lot less about baseball and more about the experience. Between innings, there are little skits and contests to keep you entertained, even more so than the actual game itself. I'd call it quirky. Even if you don't like sports, sitting in the duck blind is a great way to spend a summer evening while sipping (or chugging) bottomless local brews and hanging out with friends.
