I live in Bowie, MD outside of DC and about 40 minutes from Baltimore

I am watching the Bills and Giants on NFLNW right now. At the top of the screen they are scrolling a message that the Ravens v Colts game will not be shown in my area and a football life will be shown. That is because the local WDC affiliate channel 9 is showing the Ravens game live. If I wanted to watch that game using game pass on my iPad I also would not be able to do it.

The same will apply for people in LA and KC as NFL network cannot show the game live when the local stations have broadcast rights like they do in the preseason

You should be fine in Iowa
