Wisconsin's rain/ice storm left me with some thick patches of ice. I have heavily salted them, and broke my ice pick trying to break them up. I am starting to run low on rock salt as every place around seems to be sold out so I would rather not have to keep pouring on the salt. Luckily the main sidewalks are clear, but areas like the dumpster corral are still icy. Anyone tried a heated blanket to melt ice/snow? I found a brand called power blanket that looks interesting, but does it work? http://www.powerblanket.com/product_info.php?products_id=124 All three icy spots conveniently have a storm drain next to them so run off will not be an issue and a power source is nearby.
