Long Cross Country Solo

I planned a long cross country flight to Duluth, then Brainerd, and back to Crystal.  Flew yesterday.  Duluth is unique because it is class Delta airport with an approach controller... which makes them a wannabe Charlie.  After my first leg, I stopped to go into the pilot lounge and check the weather to prep for the next couple legs of the flight.  I pulled out my E6B when a woman approached me saying, "I haven't seen one of those in 20 years!"  I completed the last legs of the flight, which were uneventful, for a total flight time of 4.1 hours.
