My hands clamp down and a shrill scream fills my ears. Only when I pause to take a breath do I realize it's my own voice. Then we're moving easily down Divisadero Street and I can somehow breathe again. The City whizzes by and I slowly relax. I trust him completely. "This is amazing," I shout at the back of his wet head. He bobs it in agreement and pushes us faster. Thank goodness for wind visors or I'd have a face full of saltwater splatters. Most people who visit the Bay Area are surprised to discover just how cold it can get here. Mark Twain is credited with saying, "The coldest winter I ever spent was a summer in San Francisco," and it's holding true tonight. The air is already chilly, but factor in a headwind of forty miles an hour and it makes for a very cold ride. Especially when you're underdressed and the front half of you is soaked. If I'm shivering, how cold must Drax be? The ride takes about twenty minutes, and by the end, I'm a frozen Popsicle, but still, I'm exhilarated.
