We all get the Guardian. You don't get the WP or NYT. Figures.
I'm surprised you don't post on MOAB where you give us all quite a laugh with your posts and mistakes.

The official elevation of Denver is measured on the West steps outside the building, where the fifteenth step is engraved with the words "One Mile Above Sea Level." From this step, at 5,280 feet (1,609m), the sun can be seen setting behind the Rocky Mountains. A second mile high marker was set in the 18th step in 1969 when Colorado State University students resurveyed the elevation. In 2003, a more accurate measurement was made with modern means, and the 13th step was identified as being one mile (1.6km) high, where a third marker was installed.

After this midterm you can get very high in Colorado now that magic mushrooms are legal for consumption and cultivation.
