Please help me ID this snake

Ok well I was doing some fishing at a local river in my town today and I saw a snake crossing the road. I went to go investigate and found that it looked extremely similar to my corn snake, just a different color morph. I live in Massachusetts on the north shore area 30 mins north of Boston. I didn't think that corn snakes were native to massachusetts so i took the snake home and I'm keeping it safe for now in case it is a corn that escaped from its owners house or something. If it is a wild snake I'll bring him/her back to the river area, but i just cant figure out what species of snake it is. here is a pic.
