When I was a nipper we had a guy that used to visit the local schools and he used to bring the odd animal along. He'd talk to us about natural history, animals and wildlife in general then he'd get maybe a magpie or a falcon out of his van and talk about them, then depending on the time of year, maybe a lamb and off he'd go, telling us all about rearing lambs. I thought "I could do that'. I'd love to do something like that but I'm getting on a bit now so maybe not.
