I worked there for a couple of years, great place, jusy needs dragging a few hundred miles south!
In the end I got fed up of leaving the island in the rain to visit family in the S of England who were barbying and daytripping to the beach, then I would return to the island and the rain.
Yes there WHERE good days, and then the island is FANTASTIC, but these tended to be few andfar between.
Take it for the job - you MUST do that, and who knows, you may be one of those that falls in love with the place, but I suspect you will be looking to move on after a year or so.
N.B. social life is GREAT, but don't expect to go ANYWHERE on the island and not have it known about the next day!
