I was over on Arran last week visiting someone. I had to be back within the day. I spent the whole time worrying about the return journey on the last ferry of the day and wondering if I might get stranded if it was cancelled at the last minute. I couldn't relax and enjoy my visit. Got me thinking about the logistics of living on an island, even one as close to the central belt as Arran, and the nightmare which is Calmac and its difficulties. There seems no end in sight, especially for Arran but also other islands.
