“I just wish I had time for one more bowl of chili.”
(Carson died at Fort Lyon, Colo., and was more a New Mexican than anything else, so he probably meant he wanted New Mexico chili, and not real chili, which comes from Texas.)
Wikipedia disagrees with the above last words.
"His last words were 'Goodbye, friends. Adios, compadres.' Carson died from an abdominal aortic aneurysm in the surgeon's quarters of Fort Lyon, Colorado."
