This seems a fine recipe for a walking tour: six modern buildings in downtown Indy, two landscapes, six docents, and, according to Connie Ziegler, who's helping to organize the Pop UP Mod Tour under the auspices of the Indiana Modern Committee of Indiana Landmarks, “no stuffiness” and beers at the Chatterbox afterwards. The walk starts from 2 p.m. — and the map, including the meeting point, will pop up on the Facebook page (or via the QR code that accompanies that picture of the Barton Tower), sometime later this week.
