One funny thing that happened:
I left the conference to go home Monday afternoon - I had a couple of phone calls to make and the email was piling up.
I walk into the center open area of my apartment complex and there was a bus and about 2 dozen people with APA badges and a tour guide. So I asked a woman on the edge of the group what this was all about. She says, very nicely, "This is the American Planning Association. We are planners." I pulled out my badge to show her I knew about the conference. Turns out this was an affordable housing tour. One of my neighbors saw another tour on Sunday.
