This tour is a must for anyone interested in architecture, city planning, S F history, etc. Approx 2.5 hrs. Not a hard walk at all. Excellent tour guide Rick Evans. The highlight of the tour was the Hallidie Bldg (see my photo), the first 'glass curtain' building in the city built in 1918, and left in disrepair until 5-3-2013 when it was unveiled anew. We took the tour on 5-10-2013, so we were quite lucky to be able to see it.
