I will be 75 in a couple of weeks. Have done all the driving of a motorhome w/toad or towing a fifth-wheel since 1994. Hubby did not like to drive and was a good navigator. He preferred sitting in the passenger seat and I preferred driving. Now that he passed away, I am still out on the road by myself with my cocker spaiel. I hope I have at least 5 more years of wandering and maybe 10? I think we will all know when to hang up the keys...just whether we want to or not. But, it will happen.
