We have developed a relationship with this particular rattlesnake. It has spent a lot of time exploring and hiding from the heat around our house. It went to frantically rattling from a distance to let us know where it is, to a simple, single 'cht' as we walk by so we know. It had let me know it was under the house, while I was doing laundry today. I heard a 'cht' about 10' behind me. I thanked it for letting me know, and I told it I was glad it found a place to escape the heat. For some reason it came out and is now sitting 2' from the dryer. It's a crap shoot whether we will have clean socks in the morning, but it was patient and placid enough to let us take this picture.... Sure is handsome.
