It was just two years ago that the Greater Boston region was in the thick of a high-stakes showdown over whether to proceed with a bid to host the 2024 Summer Olympics. In January 2015, Boston was designated the US entry in the global competition for the 2024 Games.

It was all downhill from there.

The bid’s boosters seemed to do just about everything wrong, from adopting a secretive approach to bid documents in a city that demanded everything be put on the table to the mayor disparaging residents with the nerve to ask tough questions as a tiny group of naysaying cranks -- “10 people on Twitter.”

By July, it was over and the bid was withdrawn. It was an astonishing fall given the set of Boston political and business power brokers lined up behind the effort. In the end, the public was widely skeptical of the idea, which would have put the city and possibly the state on the hook for any cost overruns. No one did more to plant those doubts than No Boston Olympics, a small group of 30-something-year-old Bostonians who became convinced of the folly of the Olympic pursuit.

One of the group’s co-founders, Chris Dempsey, has now authored an account of the drama together with Smith College economist Andrew Zimbalist. No Boston Olympics: How and Why Smart Cities Are Passing on The Torch is a great telling of a still-fresh piece of Boston history. They came in to talk about the book for this week’s Codcast.
