Section 109 will be behind the Texans sideline at right at the 20 yard line (closer to the North endzone). Row V will be the 20th row up from the field, and will have great viewing angles from near the middle of the field and at a very good height to see all areas of the action. These seats will give you excellent views of scoring plays at the near (north) endzone, and acceptable views to the far endzone.
The entry tunnel to Section 109 is located at the very top, so you will have to walk 14 rows for trips to the restrooms and concessions, which could be far longer if you find yourself in the rows closer to the field.
Overall, these seats will be decently accessible from the concourse and have very good viewing angles to all the action down on the field.
