Obstructed and Partial Seat Views
Although the lettered row numbers K thru A are not marked obstructed, the sight lines for these seats are not good (which are the first seats). These rows are structurally flat, so people in front of you can block your view as well as the teams and staff on the field. For football do not sit in any row before row 10.
Rose Bowl Seating Chart Seat Numbers
The seat numbers in Rose Bowl follow a simple pattern, yet it's very unique. Seat 1 of Section 19 is on the aisle, and it's on the side closer to section 18. Seat number 16 in section 19 will be next to seat number 116 in section 18. In section 19 seat 101 is on the aisle closer to section 20. Seat number 116 in section 19 will be next to seat number 16 of section 20.
Which Section to Sit In
Assuming you are trying to get closest to the 50 yard line here's what you need to do. If you are looking at tickets in Section 1-4, seat number 116 in every one of these section will be closest to the center. Therefore seat 101 is closer than seat 1, but seat 1 is closer to the 50 yard line than seat 16 (within a section). The same holds true for section 13 to 18. However, it is the exact opposite for sections 19 to 24 or sections 5 to 10. So in these other sections seat 16 will be closest to the center of the field and seat number 116 will be the furthest.
