Last night I went to a party and left the car outside for 7~8 hours forgetting I was in balmy -30 Calgary... And when I realized my mistake, it was too late.

Now it's the morning after and I'm not sure what to do. I have AMA so towing the van back home will not be a problem, but how do I revive it? Is it enough to get a boost from the AMA guy and the van will come back to life???
