Doug Chadwick - DFW is short for "Dallas/Fort Worth" - two neighboring cities in Texas. The small town of Love, Texas, is about 150 miles east of there. I assume that's what the play on words is.

There's also the town of Harmony, Minnesota. I can't remember who it was, but I heard a song about setting up housekeeping with one's sweetheart "just a little out of Harmony", or words to that effect.
