Met him at the Columbus Zoo about 8 years ago. He gave a tour of the zoo, (for a fee) and afterwards, we had a Coke and talked for maybe 15 minutes. He loves that Zoo.
I always enjoyed when he appeared on Johnny Carson,so informative&passionate about the animals he loved&cared for,sad to learn he has this dreadful disease
I watched him this morning and teared up thinking he won't remember any of these adventures.
Now that I know I could see it in his gait and things he said. I'm sure they were doing editing throughout. His wife seemed to be taking the lead.
