Greetings Greg,
This is one of the many offerings that I had mentioned to you and Alsison in the past. Anything given by Chris Carlsson +/ LisaRuth Elliott/ Shaping San Francisco / info source FoundSF...boat tours, bicycle tours, walking tours, lectures, neighborhood walks, or any kind of presentation given or recommended by them, is well worth being exposed to!
Thanks Lucy, for bringing it up to the fore again.
Anita
