not saying the parent poster's solution would 100% work, but as an anecdote:

I live in Boston. It snows here and I do often buy more than one bag of groceries at a time. Fortunately, I just walk two blocks down the street and go into one of the two grocery stores that are right there.

Compare where I grew up in southern NH: it snows there, too, but the nearest grocery store was a 20 minute drive, so of course I would drive there. Rural NH is not a city, though.
