Directv Locals in Yuma, Az

I don't know about all this switching, I had my wingard traveler switched on before leaving home, got to S.C. called them, they wanted the zip where I was so I could get local channels, did so and got them. The fellow said, when you get to where your going, I'll have to call with the zip so I can get local channels. Nuts! I got to where I was going, got set up, turned it on and picks up all the local channels without calling and giving them the zip, seems the blind are leading the blind over at Dish.
