What should you have in the trunk of your car?
To answer it, we sat down and spent hours debating the pros and cons of each item... and came up with this list: http://www.cartalk.com/content/features/roadside/trunk01.html
Along the way, we also came up with our official, Click and Clack Guide to Jump-Starting Your Car.
We can't guarantee that this information will keep you from passing through the digestive system of wolves, the next time you break down. But at least your next-of-kin will be able to say you tried your best.
