You are right, your "Local Channels" are in Bakersfield. Mine are in Seattle. My understanding, and I may be wrong is that the spot beam for local channels only reaches about 300 miles.
With Dish, we have a choice to continue to get ABC, CBS, NBC and FOX, stay within the mileage range to get the network channels, or pay the extra money through All American Direct and get them wherever we might be at the time. This is real similar to the west coast vs. east coast feeds. We have a choice of New York, or San Francisco....pretty sure there are others, but those are the two we chose.
There is surely someone on here who has a better understanding than I do about this subject......TV's aaaarrrrggggghhhhh!!! Lets get back to talking about something sensible...how about computers?
