What is the difference between section 8-L and 8-H at the Rose Bowl?

Each section at the Rose Bowl is made up of a High (H) and Low (L) side. As you come out of a section tunnel, low seat numbers (under 100) are on the left and high seat numbers (above 100) are on the right.

In most sections there is no difference between the high and low sides. However, in Section 8 the low-number seats are chairback, while the high-number seats are bench style.
