Didn't realize that the Texans actually listened to the fans and changed the roof open policy
"Houston Texans Roof Policy (50/80 rule):
We will consider opening the roof at Reliant Stadium when the game time temperature is projected to be between 50 and 80 degrees. Our goal for implementing the “50-80 Rule” is to provide the most comfortable environment possible to enjoy Houston Texans games. Please note that the threat of rain will influence this decision, and when there is a good chance of rain during a game, the roof will be closed. Also, our parameters for late afternoon and evening games may shift slightly because of the absence of direct sunlight. However, we plan to use the general parameters established with your input to make the roof position decision for each game.
Our research clearly demonstrated that we cannot please everyone, every time with our roof position decision. However, we are hopeful that this note helps to point out that our approach is thoughtful, deliberate and focused on creating the best environment possible for the majority of our fans to enjoy games at Reliant Stadium."
