This is my friend Mat. Do not be alarmed--this is only a photo and he's not going to hurt you. That's his wife Harper next to him and I'm told she has a very calming influence. However, Mat is really pissed off right now about global warming, as he should be, so please do not drive your Cadillac Escalade or Hummer to his next barbecue. Don't drive them to mine, either, for that matter. In fact, you should probably sell that shit, buy a hybrid and write your congressman. In the meantime, wish for good weather in the Sierras this month as Mat and Harper head out for a long, amazing hike on the John Muir Trail, weather permitting. We need to support those who get out there in the wilderness, because it seems there's less and less of it around every day.
