So, it wasn’t mainly concern with him but I could see that after he retired, I might not be promoted to the curator level. So, I started giving some consideration to maybe going to another institution, maybe more back into the Midwest. And as it happened, the St Louis zoo, the director came and visited the zoo and he and I talked and he was interested and I was interested. And in February of 1974, we re relocated to St. Louis and left Philadelphia Zoo. I really hated to leave Gus’s mentoring and our friendships didn’t end but I really missed the guy. And so, we went off and started a new life at the St. Louis Zoo.
