Corner seating on the lower level is found on the South side of the stadium and in a single grass hill on the North side.
While the lowest rows in the corner will give you exciting views of touchdown plays in the near endzone, the upper rows have better overall views of the field. Especially in sections 10, 11, 18 and 19, you'll get a very good angle towards midfield and enough elevation to see the other side of the field when you sit in row 30 or above.
The hill next to Section 28 is a popular destination for families. Though it won't win any awards for best seats in the house, it is a cheaper alternative to buying reserved seating in the lower level.
