Quite right too Caryl, Attenborough is good, but so is Nick Baker - and I like his down to earth delivery too. Its all very "honest" the way he does things and presents them. I think Attenborough has a tendency to come across as somewhat officious at times, Steve Irwin came across as way too OTT, and Jeff Corwin can just be downright stupid. Having said that, to have the knowledge or experience of any of them would be a great achievement in itself.
