I've gotten some great DX living in Charleston, SC. I've never gotten any Austin/San Antonio stations, but back when analog was still around, I picked up KFDX 3 from Wichita Falls clear on the beach, along with a PBS from there.
In North Myrtle Beach, I picked up KWRD 100.7, plus a couple of others (don't remember the others) during that epic 2005 outbreak. That same day, I got Omaha, Kirksville MO, and one other on Channel 3 over Wilmington.
I've also heard Tulsa stations several times, including 96.5, 95.5 and 92.9.
