I went to several games at Candlestick, and yes, cold doesn't describe. On one August afternoon I learned that you also wear pants and bring a sweatshirt. I bought the grossest cup of hot chocolate ever, and held on to it with dear life as the nasty brown liquid kept my hands and stomach warm. I used to love San Francisco, and in some ways always will. But having lived in quiet rural settings for the last 20 years, going there now is quite stressful. No elbow room anywhere.
