At 68 years, I agree that questioning is valid and necessary. What I want to make sure of is that I don't mistake the occasional "oops!" with an overall decline, that should spell the end of driving for me. I have absolutely loved driving since the old red Farmall tractor on dad's lap at 6! I have driven taxi in a military area, concrete mixer, and appliance service van, plus all the "civilian" driving. Still, the first thought has to be when is enough, enough.
Happy, safe travels to you, OP, and other campers!
