I crossed the trail behind Trader Joe's in Arlington Heights a couple of days ago. The stairs from Trader Joe's are meticulously clean from edge to edge, unlike the landing below with its narrow lane between ice banks. The trail itself is fully covered in hard-packed snow and ice. This might be the worst location in Arlington not to plow because the shade of the high wall preserves ice on the trail there after everything else has melted. Continuing across the trail, the Hurd Field parking lot is a wilderness of snow, ice, water, and seemingly random obstacles. My guess is that parked cars hindered plowing and led to the lot's sorry state.
