Bush Flying, excellent apprenticship I would say, but Reddo hits the nail on the head. Particularly if you are a UK based pilot. There seems to be a bit of a suspiscion of bush flyers, so don't do it for too long.
That said, you will probably get to go to places that you wouldn't be allowed (or want) to go to as a tourist or traveller and meet some amazingly wonderful peolple, some amazingly corrupt people, see some amazing country, and some desperate and frightening sights. It depends where you want to end up, so don't get too romantic about it, but plenty of bush guys are flying with the airlines in the UK now, so give it a go.
Feel free to E me if you want to know a bit more about it, and what I did.
Good luck.
