you could try arrse or ukclimbing.com I guess, will prob find lots of people on those with at least an outdoors / active background
sounds like a fantastic idea , however after just finished reading "in to the wild"by Jon Krakauer, about a kid from a wealthy family who gives away all his money etc and hitches to alaska to live off the land . he comes to a sticky end due to daft mistakes and poor preparation. Not trying to discourage you at all , if i had the chance ,time and cash id jump at it . just remember "Perfect Planning Prevents P#ss Poor Performance"
Does anyone have recommendations of particular places in alaska/canada or scandinavia that would be good? remote, good wildlife etc? have you been anywhere that was excellent?
Iv'e always fancied visiting the Tiaga forests/Siberia. RM did a programme from there. I think to be TOTALLY on your own means you must be prepared in every sense,mentally and physically. It really does sound fantastic and something that could shape the rest of your life. Go for it and good luck
