 It's a little before sunrise, and I'm following John Castine along a trail, looking for a place to hunt deer. John is in his late 30s. He's both clean-cut and weathered, thickly built and fit. And with his rifle and hunting clothes, he doesn't really look like a college professor. So what I'm going to do is just go up this trail along the ridge for a little while until we see something that looks like we've got a good view, and then settle in.
