When we got to Houston, we traded the Impala we'd gotten (as the last one-way car National had at DFW, and they were charging $188 a day for it!) for a Cadillac STS (that didn't cost me anything but fuel and taxes, thanks to free rental days), and then spent the next couple of days visiting friends and family all over southeast Texas.
We're now at Houston Intercontinental Airport, waiting for the return flight. I'm hoping the freezing drizzle forecast for southern Minnesota doesn't materialize before we get home.
