The Rochester Fire Department already had their snorkel in place and had just started shooting water onto the flames. In my photos, it looks like the warehouse right in front is on fire, but it's actually right behind this one (see the map above).
Mr. Johnson graciously agreed to take a short detour on the way home so I could get one more picture of the fire aftermath in the daylight. "Results of the investigation" as to the cause of this fire are "still pending," according to local media. Fortunately, no one was hurt and no other businesses in the area were involved.
I applaud the efforts of our Rochester Fire Department. It's gotta be tough getting woke up at 3:45 in the morning, knowing you have to go fight a fire in a warehouse full of chemicals when the temperature's about 12 degrees and you have no idea how long you're going to be out there. This last photo was taken about 2:30 and some of those firefighters were still on the scene monitoring hotspots.
