I have a cousin - he knows who he is - who loves snakes. He keeps them for pets, has been known to take them aboard planes, pre-911, in his carry-on luggage, and has loved those fun Texas Rattlesnake Round-ups! I think he's crazy. But, I sure wish he'd been here today.It's so hot here in Middle Tennessee. How hot? So hot that I saw something I've never seen in all my years of watering gardens. There, lying under the mist of the faucet-water hose connection, was a 3-foot rat snake; and I didn't see him until I had put my hand 2 inches above his head to turn off the water. I'm sure my scream echoed up and down this valley, and I had no idea I could scream like that. At least it disturbed my unwanted visitor, for he slowly slithered off with a "Sheesh, woman!" look in his beady little eye.
