I'm 38 now, and my dad absolutely loved this show throughout the '70s, but I always found it boring. I'd sometimes watch with him when I was younger, but then I became disinterested.
My dad passed away a few years ago, and how I wish I had spent more time enjoying the show with him. I miss him terribly. He loved all the nature shows, but this is the one that I remember him watching most often. He never missed it.
Pure nostalgia drove me to look up the intro online on YouTube tonight, and then to find the website and come to this page.
THANKS. I truely enjoyed that. I used to watch this show as a little boy. I am very sorry to Hear about your dad. Steve Portland. Oregon I'm a Cinemajunkie !
