Wow! Thanks Trevor and psr!
It really is comments like that that keep me going and make this seem worthwhile.
I remember many years ago at my interview for the job I got that took me to Antarctica, one of the last questions I was asked was something like "What do you want from life?". Being young and full of ideals I replied "To make a difference" (I'd read it somewhere and stored it for future reference!).
Little did I know then in what way my time in Antarctica would enable me to make a difference. But I know that I'm just a very small part of a much larger movement that makes it possible - Trevor with his hands-on cut-the-crap-and-do-something approach and psr at the working end of the educational process. Children are the future and the sooner we educate them and make them care about this place, the better chance we have of preserving it.
