92 Taurus Overheating...

My 92 Taurus Wagon overheated last night while driving it around town. While stopped at a traffic light I could see white smoke coming from the engine, and noticed the engine was running hot. When I pulled over there was radiator fluid both steaming and leaking from the car. It was not from the overflow, but rather from somewhere near the radiator (I couldn't tell in the dark). I added some coolant to the overflow, but it was already full. When the car stopped steaming I drove the mile to my friend's house, and when I arrived, the same thing, steaming and leaking. I don't know where it is leaking from, or what the problem may be. If the radiator were cracked and leaking, would the resovoir drain out as well? It seems to remain full. If there are no cracks where are some other places that coolant can boil out of the cooling system. I'd appreciate any advice or input. Thanks.

With lights on and the car running you will probably figure it out, but you most probably have a radiator hose leak.
