The Julian Drew block, at 178 E. Broadway, is in the heart of downtown. It's included on one of four Sunday architectural tours by bicycle or on foot with an eye for what Tucson looked like 100 years ago.
The Barker Bros. Warehouse is on East Toole Avenue, near the railroad tracks. One of the four Sunday tours - this one a walking tour - will cover the Warehouse District. Architect Corky Poster will lead the tour.
