Starting at about 14:30, Bubba started cleaning the parking lot. He started with shoveling, which had no effect. He's now running the tractor near the OSB and it's having some effect on the IFO. The range has gotten pretty ratty and POP (which is still trending down after re-locking 2 hours ago) is occasionally getting knocked around. Think we'll survive, but analysis people should be aware when looking at this mornings data.
