This type of leak is a great reason to have shutoff/bypass valves in the dash heater circuit back near the engine. Failure of a $300 heater core and/or 80 feet of aging coolant pipes/hoses can destroy a $30,000+ engine. Some engines require constant flow through the heater coolant circuit, and those models should have a bypass between the heater lines so that coolant can continue to flow as if the heater were still in the loop. It'll get you home, where the repair cost can be greatly reduced. The downside is that you lose the use of the windshield defogger until you fix the coolant leak. Small beans in my book.
