Quoting Wikipedia: "The Blue Mountains are a mountainous region and a mountain range located in New South Wales, Australia. The region borders on Sydney's metropolitan area, its foothills starting about 50 kilometres (31 mi) west of centre of the state capital, close to Penrith on the outskirts of Greater Sydney region."
A group of enterprising individuals calling themselves, "Ask Roz Blue Mountains" have created a niche market as promoters of tourism in this magical region of Australia.
And they are having enormous success. https://www.facebook.com/AskRozBlueMountains/
The reason I am posting this is that they are one of the numerous Australian businesses that see the value of What3Words as part of their marketing strategy.
With the first big snowfalls of the Australian winter yesterday, here is a screenshot of a post they put on their Facebook site with the potential to be seen by 26,000+ viewers.
