I was waiting this afternoon at 8th & Howard, South of Market in San Francisco. The intersection marked one of the entrances to this year's 25th anniversary Folsom Street Fair. While I waited for my friend Floyd to arrive, I watched two college boys stumble accidentally across the entrance gate to Sin City. They debated for several minutes about paying the $7 donation and going in, or passing on their way and retaining their innocence. Alas, vice prevailed. They went in.
