When you just can't decide on one kind of material for the whole mansard. On Nebraska Avenue. What I was going when I saw this one: heading to QuikTrip for gas. Where I was coming from: dropped G. off at a friend's house, then stopped at Ruler for 5 gallons of skim milk, because that's how we roll. Where I went next: home to take on an enormous mess in the laundry room full of sledding-wet clothes.
