That sounds brillaint, I love walk through enclosures. Yeah, it's a few hours away from where I live. But I could always stay over-night, so long as there's a premiair inn nearby I'm good. Me and my Mum have been thinking about spending a weekend up near there to go around the zoos nearby anyway, Banham was certainly one of the list we were thinking about.
I've been to Colchester before, we can just about do that one in a day. I have to anyway, 'cause they're the closest fennec foxes to where I live. I've never heard to Thrigby though, I'll have to check it out.
