Yes, aerial and digital aerial is still free. The misconception may come because I would say most people in the states have cable or statelite, simply because it's better quality in a lot of places.
In big cities like Chicago, New York, LA, etc, I think most people use aerial because quality's fine there.
I personally don't get any tv
You'd do well living without it for a while, you'll realize you don't miss it
My mother said that we once went for a while without tv when we were growing up and we had a lot of fun without it, we were doing family type things. I asked her why we ended up getting tv again and she was like, *shrug*. So, I dunno, I think my children would do fine without it
It's not just for BYOND you know!
