I saw this guy last week just off the trail at Highway 64 in NC, where I was caching some food. He/she looked to be about 24" long and was enjoying the sun at about 10 on a chilly morning. You can't see the pits very well in this photo (which I couldn't seem to rotate for better viewing -- sorry), but they are there which confirms, for me, that it is a rattlesnake. I didn't disturb him, so he never rattled.
