The second deck of seating along the east sideline is the is called the 100 level. Despite being above the lower level, fans still get good views of whole field and aren't nearly as high as the 400 or 600 level.
Most fans consider these seats the best value at Memorial Stadium. The views are identical to club seats on the other side of the field, but can be purchased for a fraction of the price. These seats are perfect for someone who doesn't desire chairback seats or club amenities and just wants a good view of the field.
These sections are convenient for going to the concourse because they are small with only 16 numbered rows each.
