Rapid loss of Coolant from bottom of the car

My car loss all its coolant today while driving all of a sudden. The car started overheating and the car shut itself down. Hopefully a head gasket isn't blown.

I refilled the radiator with coolant and it started leaking rapidly under the car near the midpipe area. See picture below. I just replaced the radiator and hoses about 1/2 year ago. Am i still safe to drive the car over to my local repair shop which is about 3 blocks away or should I have it towed to the mechanic? Maybe it's the heater core hose?
