As I stated in my comment, if you are able to safely let the car idle i.e. the problem isn't your headgasket, ringlands or a burst radiator, you can tow the car with the engine running and someone behind the wheel. From a mechanical perspective this is no different than coasting. I believe the danger with towing the car with the wheels down is that you don't have adequate circulation of your oil to keep the transmission cool. Having the car running will make it safe(r) to tow. A nice bonus is that if you're using a rope to tow the car, the guy steering will have the powersteering active and make his life much easier.
Just don't go fast and try and keep it as short as possible. I would say go 5 miles, then stop and wait 10 minutes. Repeat until you reach where you're going.
