Wild World and Sodor

Laziest shot ever, but I am busy planning and looking for wild out of the way places to visit. I would like to visit as many of the islands around Britain and Ireland as I can. In the last 30 days I have visited Mull, Lunga (Tresnish Islands), Staffa and Ulva. 

At the end of next week I am going to the Farne Islands with a small group of people. 

I have a slight problem with just a few of the islands mentioned and described in my newest book. Sodor is one of them. It's a fictional island somewhere near the Isle of Man, and since I have been to the Isle of Man,  and since I have spent many an early evening reading the 'Thomas the Tank Engine' series, I think I am going to tick it off as already done. :-) I am pleased the authors felt it important to include Sodor,  but, perhaps, I need to find out more about its wildlife.
