The visited islands in TX seem strange. Were those really both cases of fly in for the day and fly out later?
Yes. I went through a phase in my career when I was doing a lot of short business trips. The trip near Waco included a visit to a potential building site and a meeting with the city government. We were in and out the same day.
Something similar happened with suburbs near Dallas and Denver.
Also, I once drove up with the groom's family to a wedding at the Minnesota Renaissance Festival. The round trip was close to 20 hours (I think), but it was all done in one day.
