During yesterday's bike rally (report to come), I was stunned to hear my home boys say that Texas is in the South. I've lived in Texas for almost 21 years, and I'm no Southerner. What is your pretheoretical intuition? Is Texas in (or part of) the South?
Addendum: Don't read this until you've answered the question.
