Not dangerous, just beautiful this colubrid.
The Corn Snake or Red Rat Snake (Elaphe guttata) is a species of Rat Snake. The Latin word elaphe means deerskin. A corn snake suffocates its prey by wrapping its body around it. Constricting prey is a basic instinct for snakes and they will preform this action in the wild and in captivity. Like any animal its temperament and behavior is different for each snake. Corn snakes are generally docile and make excellent pets. Their average adult length is about 1.2 to 1.8 metres (4-6 feet) fully grown, and they can live up to 20 years. They are found throughout the south-eastern and central United States as well as parts of Mexico. The name 'corn snake' refers to the splotched pattern on its belly, which resembles Indian maize. Some, however, believe it is because they are often found in corn fields where they search for rodent prey. [Wikipedia]
