I have had an interest in mountain Bothies in Scotland since away back in the 60's. I have gathered the data of around 400 shelters/Bothies nowadays onto Excel files after many years of obtaining the information by word of mouth, from old collections made and kindly given to me by other folks and of course by using many of them during forays into the Scottish Hills.
The images produced of the Bothies by the gentleman are very fine.
My local Bothy is currently under going a massive makeover by the Estate folks who are funding the reconstruction.
