Not since I was about 14 years old!

How young do you think I am!
The super-wet and super-sunny summers would both have been somewhere between 1960 (me being old enough to remember them) and 1969 (my last childhood summer there). If you can't track them down I might have a look myself later.
There aren't as many routes as one might think, given that there is a huge area taken up by lochs, mountains, and the sea!
Hopefully the weather will be kind enough to tempt me into doing some long rides.
My sister said that on a sunny day she might fancy (annoying
@oldwheels by) visiting Mull, in which case I'd go over with her and either do the southern loop or even ride anticlockwise as far as Tobermory.
I have a few other routes in mind, subject to conditions.
