Old guy, don't give up. My wife has had MS for over 20 years and has reached the point she cannot walk, even with a cane. She can make it for a few feet with a rolling walker. We just got over a bout with breast cancer and were ready to sell out and find a place to stay. She told me a few days before Thanksgiving last year that she wants to do another trip west for a few months. The planning and discussing of this trip has invigorated me and refreshed my outlook as well as actually make her feel better and get a bit stronger. I know we will have to quit one of these days, but as long as she is wanting to get out on the road then I will do my best, with the help of the Lord, to make it happen.
