I tried to get my phone to take a picture, but by the time I did, the snake was gone. It was sitting in one of my raised beds.
I live just west of Philadelphia.
The snake was about 6 feet to 7 feet long. It was about 10" - 14" in circumference. It had dark eyes. It wasn't poisonous by the looks of it. It was all black. And my guess is that it weighed about 10 pounds. It looked like a constrictor of some kind. My guess is it might have been a rat snake, but I have never seen one even close to that size.
I have lived in this area my entire life and have never seen anything like it here. I think I saw a similar snake while on vacation in Florida.
