Chicago/Philadelphia reveals...doing both!!
I will drive Friday 2/8 to Chicago from Detroit, see the show (I mean Challenger) Saturday am. Saturday afternoon drive back to Detroit, stop at Metro airport west of Detroit, park, use my brother's Northwest buddy pass, late night flight to Philly, rent a car, drive to see Challenger at Philadelphia, and fly home Sunday night, get in my car and come home.
Work Monday morning.
