BBC Pop Up explores Boulder's affordable housing crisis

In the 1960s, the Colorado city of Boulder was a destination for hippies. Today, it's tech start-ups and entrepreneurs who are flocking to the town on the edge of the Rockies.

It's easy to understand Boulder's appeal - stunning scenery and a laidback outdoor lifestyle, but not everyone can afford to live there.

House prices have soared in the past decade, in large part because strict planning laws restrict the city from growing any further.

Boulder is renowned for its liberal attitudes but now, confronted by deepening wage inequality and an affordable housing crisis, its residents are debating what values are most important to them.

The BBC's David Botti reports.
