Before you go out to shovel the snow from your driveway and walks, take a few moments to prepare yourself for what is often a good workout. Do few stretches, drink plenty of water and dress in layers. Boots with good traction are a must, as are gloves that allow you to firmly grasp the shovel's handle. Never try to lift more than you can carry and avoid smoking as it reduces oxygen needed for such strenous work.
A 4-ft. T-square for drywalling can come in handy for other projects. Besides being helpful in drywalling, it can be useful when laying out patterns or cutting on full sheets of plywood or particle board. The square is accurate, stable and will give you a full 48-in. straight line. Some newer versions come with a head that can be adjusted to various angles, then clamped in place.
