There's nothing quite like a nice hike through a snowy wonderland in the dead of winter. There's also nothing quite like busting your arse on the ice when you do it. Boot chains can help keep you upright, but there's no need to shell out for a pair when you can just whip up your own for a lot less.
All it takes are a few bungie cords, a bit of cross-linked chain, and the patience to spend a couple of minutes hooking them together. You can get all of that the hardware store for a couple bucks. (Except the patience.) In the end, you get that little bit of extra traction that could save you from embarrassingly GIF-able spills or worse, a fractured tail-bone.
