Large, sudden coolant leak

Just got to work and saw a bunch of steam coming out from under my car. Checked underneath to find a large puddle of green coolant and much more just pouring out from my car somewhere. I don't have a jack so I can't get under to figure out where that's coming from. Obviously a problem, but my question is, should I get it towed, or would I make it to a shop? I'm guessing by the time I start it again there will be basically be no coolant left... Closest shop I know is maybe 15 minutes away.



Thanks guys.
