So U2 apparently isn't the only band from elsewhere that digs North Carolina barbecue. Check out this excerpt from a recent tour-diary entry by the Nashville rock band The Ettes:

It is dark, and we shall soon arrive in North Carolina for a brief
night's rest. We come to western N.C. whenever we can, to chill, stare
at mountains and eat barbecue. What is important for you to know is
while there is indeed a difference between Memphis, St. Louis and
Carolina barbecue, Carolina is the best. Growing up we would say,
"God's favorite color is Carolina blue!" referring both to the Tarheels
of Chapel Hill, as well as the actual clear blue skies surrounding the
Blue Ridge Mountains.
