I keep up with it because so many DIRECTV subscribers don't and offer false statements about what is and isn't literally allowed.
You read your agreement with directv, did you?
The Customer Agreement has points that exclude tailgating (in the sense of packing up your home equipment and taking it to the game):
- The mobile units clause (1g) says that mobile units cannot be part of a residential account.
- The private viewing clause (1h) says that viewing must not be in areas open to the public and must be used for private home viewing.
