It's the 5th anniversary of The Road to Now so Bob and Ben invited a brilliant lineup of past guests to answer one question: "What has been the most unexpected turn you've seen in the last 5 years and how has it changed the way you understand the past?"

The lineup:

Senator John Hickenlooper

Heather Cox Richardson

Jefferson Cowie

Stacy Wood

Joe Kwon

Matt Negrin

Doug Heye

And, as you may expect, we covered more than just that question.

Thank you to all of you who have listened to our show and kept us going for 5 years!
