Oh, I don’t worry about it for just a day or two. I do have some of those things you can stretch over the bottom of your shoes that are supposed to “bite” into the ice. However what I find even better is to walk across the snow in my front yard, avoiding driveway altogether. I walk across the yard, staying on grass - though there is somewhat of a hill on other side of the yard - but not near as steep and ALL on a grassy area between my property line and side of neighboring yard. Then I can walk across the front of my property, still on grass until I’m opposite my mailbox on other side of road. I cross the plowed road, get my mail and reverse the process 🤪 However, if there’s black ice on the roads, all bets are off and the mail can just stay there!
