We had a calmac ferry (Clansman) sailing to Iceland a few years ago for 14 hours it was that bad, I'm right up by the Butt of Lewis 58° North, its starting to get darkish around midnight for a couple of hours now, but solstice time is a pain, I much prefer winter when theres no heebeejeebies aboot, and the winds up to 160mph, I wonder why we have no trees ?
