Ro646a, I am so sorry for your loss.
Right now we are in sort of a holding pattern while my wife's younger brother is under Hospice care. He is 7 years younger than my wife and was not yet ready to retire. We had talked many times about our travels and he was all prepared to buy a motor home and hit the road in a few years with his wife. Now, it is not to be and he has been selling off his boat, his Harley, and other toys so as not to be a chore for his widow after he passes.
The facts are that none of us know when the clock will stop. All we can do is make the best of each and every day and hope that there will be a tomorrow to enjoy. My wife and I have been fortunate to be able to travel throughout the USA and to Europe and South America. Our original bucket list was long since completed and now we have a continuously updated bucket list of things to do and places to see.
Thank goodness that you made the decision to go Rving when you were healthy. Many people wait until it is too late. Memories are never lost and your memories of your good travel times with Lois will be with you forever.
