Key Discussion Points & Insights

1. The Podcast’s Evolution and New Identity

• The show has officially rebranded to "The Big Dig" as a stand-alone title for the entire podcast feed, removing season-specific names and cheerfully embracing its legacy.
• Ian Coss explains the shift from a single-project podcast (focused on the Boston “Big Dig” highway project) to an ongoing, multi-season docuseries.
• The purpose: To connect the dots across seasons and offer a multi-dimensional portrait of Boston—and America—in eras of major change.

2. Expanding Storytelling Universe

• Coss envisions the seasons as interconnected, sharing:

  "In nerdy terms, I think of this kind of like the Marvel Cinematic Universe, but for Boston politics. In the 80s and 90s, characters will start to pop up again and again. Storylines will cross over." (03:36)

• The show aims to create a complex narrative web, allowing listeners to see how politics, history, and personalities overlap throughout Boston’s changing landscape.

3. Central Themes: Boston’s Distinct Character

• Core to the show is the famous Boston adage:

  "This is a town where there are really three [pastimes]: politics, sports, and revenge. There is so much truth in that." (04:29)

• The ambiance and stories are deeply rooted in Boston’s unique, often gritty, culture—while still being accessible and engaging to listeners everywhere.

4. Community and Listener Engagement

• The podcast has launched a new email address and mailing list, inviting audience participation, feedback, and story ideas.

5. Upcoming Live Events & Future Seasons

• The next season will premiere in January.
• A live tour is scheduled for late October, with events not only in Boston but also in Portland, OR and Seattle, WA.

  "These will be tied to our original story about tearing down highways. And they will not just be in Boston." (05:34)

• Plans for further events across the Northeast and eventually the South in the coming year.

6. Continuing the Mission

• Each season tackles different subjects (e.g., infrastructure, gambling) but collectively illustrates how various forces shape modern America.
• The show's purpose is summed up as:

  "The more you listen and the more stories we tell, the more the dots will link up to form an image that is bigger than anything we could present in a single season. The image of a great American city at a time of big historic changes in American life." (03:23)

Notable Quotes & Memorable Moments

• On the show’s new identity:

  "I think of all these seasons as connected ... like the Marvel Cinematic Universe, but for Boston politics." (03:36)
