I've attended maybe 6 or 7 Twins games since Target's Grand Opening and this section has been my favorite. I've sampled every area except for the Legends and Champions Club seats. I don't need all of those "extras" to enjoy a baseball game.
Section 3 is literally right next to the Twins dugout on the first base side. A great spot for kids to sit and collect autographs during batting practice.
I try to go to night games as they are generally cooler and it's easier for me to relax. The food is beyond great. Make sure you try a sausage from Kramarczuk's. If you want to eat before the game, check out Lyon's Pub on South 6th Street.
