6 of us took the tour during World Pride Weekend (the group ages ranged from 11-71). Joe took us from one important site to another. Yes, we learned about dates and events, but so much more. Joe made sure we realized how times were then. He had such passion that you couldn't help but get involved.
Being Pride weekend, the streets were packed, but we had no problem hearing or finding shady spots to stand. Joe took his time and was open to all questions.
Although 4 of us are gay, we ALL learned a lot and got to see where things happened. 2 of the adults are very picky and even they had noting but good things to say.
I am sure the effectiveness of the tour depends on the tour guide, hopefully they are all as good as Joe.
