If you drive a rear wheel drive car or truck, you know how much of a pain it is to drive on snowy days. This winter, instead of using messy sandbags that always seem to tear open and spill, just use a cool new Sand Caddy. These reusable, leakproof plastic containers hold almost 40 pounds of sand, salt or mix for extra weight and traction without the mess. If you do get stuck, you could also spread the sand under the tires to get some grip. Great solution.
