This might be of interest. The north German resort of Winterberg is proposing new lift and piste links to its smaller neighbours. This is a presentation of the problems, opportunities, user numbers, costs of putting in the lifts etc. Even in German, you can follow it.
Why is it relevant to Scotland? The Hochsaurland resorts are dependent on day and weekenders from the Ruhr and the Netherlands. Neuastenberg, one of the pocket resorts to be linked can get running on a few centimetres of snowmaking. And had a near death business moment about ten years ago. Investing in snowmaking saved it.
