Yeah, pretty much all of our "local" stations are in 720p (the ones from
Lexington).  A few from Louisville are 1080, I think.  On the local cable,
the 720p OTA stations are 720p there, too... the 1080 stations are all
1080i, both OTA and cable networks.  I think that must be a limitation of
the cable company or their equipment.  I don't notice much of a difference
unless I am trying to watch football or indycar, and that difference really
went away when my first HD TV died.  The replacement is not as large or
fancy, so it all looks pretty much the same and not really all that bad.  I
sometimes think the fancier TVs make the differences more apparent and, by
doing so, make things look worse than they would otherwise.

I am not sure this is right (anymore) but it seems to be like some of the
ones that were on 720p on their primary were also broadcasting a subchannel
in HD also, and it was also 720p.  I wondered if broadcasing a subchannel
in HD put any limitations on the "bandwidth" available for the primary
channel, which caused it to also be limted to 720p.

One of the local stations was doing that with their sub because they would
broadcast some extra hours of news on that station.  The sub was
otherwise broadcasting older shows that were filmed before HD became a
thing.  The quality was still better on those older shows because they did
not "center cut" the sub.
