Some of Larsen's tips include:
- Be careful. There could be ice under the snow.
- Use a smaller shovel so you are not as easily able to overstrain muscles while shoveling.
- Be especially careful with the big piles of snow left by plows by the side of the road. That snow is much denser and harder to shovel and it is easy for people to overexert themselves when shoveling that type of heavy, icy snow.
