A plow route through Avondale follows the old diagonals — Milwaukee, Elston — the ones that were trails long before they were streets, running across the grid toward the river's north bend. Lk Landscaping & Snow Plowing takes that route while the neighborhood sleeps: plowing out drives, shovels through the walks and side gangways, salt across the sidewalk squares that catch the runoff. Storms here often start as rain and then turn, which puts a slick layer under everything and makes the salting the part that matters most. Coming to the end of a route at first light, with every drive open and the pavement dark again, is its own kind of good. The next one is usually a week out, and then it begins again.
