Making My Dads Dream a Reality

Sorry for your loss let me ay first. Best avice I can offer is drive the car enough before you go to feel 100% comfortable with it. Mechanicals and your body too!! Take a 3 hour road trip, and see how you fell after that tie behind the wheel. The drive another couple hours!!
I lived in Missouri for 39 years, 10 of which I travels old 66 to work!!! I saw many "pilgrims" travel that road!!! This will be a wonderful adventure I bet!!
