Ice is one of winter's hazards—both on the road and on your car. It's always best to park in your garage or covered carport to prevent ice from forming on your windshield and rearview mirrors. But for those who are stuck with parking en plein air, here's a clever trick. Just open up a few ziplock bags and slip them over your mirrors. The plastic covering will keep most of the ice and snow from sticking, making those frigid mornings way less frustrating.
