Many of us were detained getting to Assumption Grotto which is on Gratiot just south of 7 Mile Road. On the east side of Gratiot and just a few buildings south of the I-696 service drive, B&D Upholstery building was engulfed in flames (according to an article in the Detroit Free Press online, it was unoccupied). People had seen it on fire at 11:00 and I passed by just after Noon when I got caught these pics. Gratiot was shutdown for several hours - on the southbound side with fire trucks and on the northbound side due to heavy smoke.
UPDATE: View a slideshow of the fire which includes these pics and more at my Smugmug site (set the speed to fast in the upper left hand corner).
