Help me understand DirectTV local programming

Thank you all for the replies. Where I'm confused is that the waiver paperwork said that if I was using a receiver from my home I would need to setup a separate account. I certainly don't need a new account for an occasional week or 2 out camping. I understand that Dish Network has a pay-as-you-go service that allows you to buy only what you need a month at a time. Why can't Direct TV get with the program?

Thanks

Steve
