Bruce take care of your wonderful wife, even if I have never met her, she sounds like one of the very few special ones. Mine has put up with me over 40 years and the good Lord has blessed me with our health. I can't imagine ever being in your spot, so I will think of you and yours as well as pray for you.
Take care maybe the chemo will make a cure. I have a neighbor up the street that went thru a year of chemo and therapy. She has been clean over a year now. There will be time for planes when she is healed/cured. Yours, DOC Holliday
