My two longest drives were last year when I was looking for work. I had to drive to an interview in Tulsa, OK from Dallas and again to one in Monroe, LA. Both trips were about 5 hrs each way. I would leave my sister's house, stop somewhere, change to fem, drive to the hotel, change in the back of the SUV to drab. Then when I would leave the interview, I would find a place to change to fem, drived back to Dallas, stop near my sister's house and change back to drab.
Never had a car slow down and look at me or anything. Most times cars would be going faster than I was and I was already doing 10-15 MPH above the speed limit. LOL
