I was at BIR yesterday, thankfully racing was done for the day, the track had given us plenty of warning that the storm was coming and all the racers had left, so no one was injured. The grandstands pictured look to be the low ones at the far end of the dragstrip, the main grandstands appear to be fine. The couple of buildings missing roofs should be able to be worked around, they have other buildings on the grounds to use for storage, etc. Certainly a big mess to clean up, but BIR said they expect to be open this coming weekend for the scheduled event. Lots of damage in the Brainerd lakes area outside of the track at the resorts and homes, my sympathies to those effected.
