As you face the field from Section 640, lower numbered seats will always be closer to midfield (and Section 640), while the higher numbered seats are closer to the endzone (and Section 642).
At the top of the stadium along the sidelines are the Terrace Level Sideline sections. This location is known for being the best place to find cheap tickets with the best views of the whole field.
Made up of both 500 level and 600 level sections, the 500 level sections sit closer to the field and have very few rows (just 3-5 rows of seating in each), while the 600 levels sit in some of the highest elevation from the field and have far larger sections with 21-26 rows of seating in each.
While you are up high, you have a great view of the entire field from close to mid-field. You can see all plays as they unfold regardless of which end of the field the teams are on!
