Traffic is gonna be rough. It usually is anyway, but Saturday’s will be brutual, so leave yourself extra time (and patience.)
If you have kids, go to left field. There are some games for them there (if it’s still open due to…) Also, near the team store (center of the concourse), the “card guy” might be there. Usually had 4 tables set up with a bunch of cards and memorabilia. Has some neat stuff.
