You’re very lucky. I lived 60 miles south of Seattle, 30 miles southwest of Tacoma, and was able to get a single channel with an antenna because my city was in a valley surrounded by mountainous terrain and so the broadcast signals from the TV towers were all blocked by the terrain.

I also worked in local television for a long time in the early 2000s and 3 out of 4 of the stations I worked at no longer exist and there are fewer and fewer rural stations, so unless you live in the big city or unless you’re in a very flat area where the big city signal can get to you, you’re shit out of luck.
