I have a plastic bag by the back door on a nail for aluminum cans. I was putting 5 or 6 in this evening when a copperhead that was there by the door got scared and came in the house by my feet. Fortunately he was slipping and not getting good traction on my tile floor. I slammed the door closed and saw him no more. I am hoping he is out. I went out with the flashlight and didn't see him outside either. I am not totally positive that he is out, but I think he must be. THIS IS A FIRST FOR ME.
