My brother and I toured the Temple Square in Salt Lake City in 1999. A couple of German female Mormons spotted us and showed us some of the more prominent sites. My only complaint was that they were quite pushy about evangelising us and wanted to get us to fill out forms with home addresses and phone numbers.
Did you notice how Church street and State street ran parallel to each other through Salt Lake city? I commented on that to my brother when we were driving.
My tour guides were a couple of young girls, one American and one Brazilian. They were very nice, although there was a bit of a whispered "Join us...join us!" mentality to them. I do recall them wanting our addresses and phone numbers, now that you mention it (they didn't get them).
I also recall protesters marching just outside Temple Square, telling people not to go in and ranting about the evils of the Mormon Church. I told one of them that he was being quite rude, and he tried get in a debate with me about the incompatibility of Mormonism and the Bible. When I told him that he was wasting his time because I’m an atheist and don’t believe in either one he got a very nonplussed expression on his face and went back to shouting at the crowds.
