Good for walking the icy, snowy, steep driveway along with a pair of long ski poles held in each hand and a backpack for haul'n the groceries up and down the steep driveway.
Leave the car up top at the road, and tie on a pair of Yaktrax Pro friction walkers, similar to tire chains for tires. Reg price, about $35 ..... eBay price, about $20 in four different sizes.

Maybe get a black plastic, drag behind sled for moving large items similar to what snowmobiler's use to move all their fishing gear out onto the lake ice, or somewhere down the trail.
