In case you ever wondered where the codename "Longhorn" came from, Windows XP was codenamed Whistler, and the follow-up version was codenamed Blackcomb, after the Whistler and Blackcomb mountains at the popular, eponymous Whistler Blackcomb ski resort in British Columbia a few hours away from Seattle.
The Blackcomb release of Windows started slipping, so an interim release was planned. It was codenamed Longhorn, after the Longhorn Saloon and Grill at Whistler Blackcomb: https://www.tripadvisor.com/Restaurant_Review-g154948-d70639...
