Hi Slicks,
I can imagine you might be bored of me by the end of this but it is a subject close to my heart. Not that i have done it and not that I am necessarily in a position to comment on success of finding sustainable work etc.
But...
If I had been in your position when I was 24, I would have (Without even the slightest hesitation) tried it.
I am now settled down, at 28 with 1 son and second on the way, commited to sustaining high mortgage etc etc, and it is still praying on mind, and i have given myself 24 months to decide and 'Make my Bed' as it were, after that time, I stay or go, and no more dreaming.
Even considering it in hindsight, I am not 100percent certain why my wife and I didnt try it 4/5 years ago. We could have had a good chance of suceeding. There were a lot of factors interupting things back then though.
Long story as short as possible though

, you truly only have one chance at life, and these things that we wish we might have attempted or experienced are best grabbed when they arise.
For me there are many things that I am comfortable with not having acheived, but there are certain things that now the chance has passed, I really wish I had tried. Something like this can truly define you, and if after a year or so it isnt going anywhere then move back to the place you know, and you can say that you gave it a good shot.
Now please excuse me if I speak out of turn here

but, As for the locals i think there is a wide enough variety of people living in and around Newquay now for it not to be too hard to fit in and find friends, the only thing to remember I would imagine is dont go thinking you are a 'local' when you are around true Cornish people. I can imagine the most offensive thing to locals is the sort of situation you get like that jetty that was refused for local fishermen in Helford (even I felt sick at the thought tbh)
My Views on the News the story is featured here with others, this site also gives a good insight, but does also have an element of rosy-specs to it.
Anyway after all that rambling - if you cant find any friends you'll always have the surf
