Daylight is fairly minimal, it's dark when I leave hotel at 7 and dark again by around 3. Weather has been so bad I haven't realy chanced driving around, but have seen a few Islands on previous trips. Best thing is at the top of the main land where Atlantic Ocean and North we meet, waves coming in from two different directions!!How many hours daylight are you receiving at the moment. And have you been around the other islands?
I can see where your comming from with the roads. Considering all the harsh weather Tarmac is awesome condition with absolutely no pot holes. I've got a hire 4x4 and if I had big enough kahonas I'd test it out properly !!!!!Only been in June for The Simmer Dim (bike rally) so get the very best of the weather. I'd move there in a blink, but I wouldn't be able to handle the long winter nights
