You never know. I thought the same thing, I live in a small town of 20 thousand and I get a ton of stations OTA. I put a big ole antenna in the attic so it would be unseen and I get stations as far away as 50 miles. I get all the majors, nbc, cbs, abc, fox, wb, and pbs. Plus a bunch of weird channels that play old movies all day.
WIth that said tho, we never watch any of it. We use it as back ground noise when we are not streaming.
