But my neighbor showed me something kinda cool.

He said if you head up to I-70 (and other highways that get a lot of snow and often have chain law in effect) and look at the guard rails in the passes often times you'll find lots of free chains.

Apparently the chains fall off semi trucks and the plows push them into the guard rails where they just pile up.

These aren't the wimpy chains you buy at Autozone either ... these chains are beefy! Of course they'll require some tweaking to fit your car or truck (since they're so big) but if you have a set of cable cutters and some heavy quick links you can get some pretty strong free chains.

Might not want to use these on a sedan, but he puts them on his pickup and they work great.
