Season 1 Episode 52:

When it comes to unsafe street conditions, Jonathan is no stranger to the world of tactical urbanism, he is compelled to do something to make the situation safer for everyone. In this episode, John and Jonathan chat about his activities in Boston and in his new home of Denver.


Show Notes:

Flowers in pots, a flower in a traffic cone, red cups, 6-foot tall cardboard comic character cutouts… just some of the safer street activism materials Jonathan Fertig has employed and deployed during his years of advocacy work in Boston and Denver.

John and Jonathan chat about what got him started in advocacy, his move to Denver, and how his life and activity levels have shifted now that he and his wife Helen are in the outdoor playground that is Colorado.
