Blades on Building

After a couple of hours at the gym, it was time to hit the road and find some blips. I drove into the valley along the Lowell-Larimore Rd. and pulled off by one of the farms and found this cool building with these saw blades all along the outside of the building , I was captivated and thought other's might enjoy my find as well.
Lots of clouds here and some rain, lots of wind though. Hoping we don't have any trees go down.
I did see 2 red tailed hawks circling around near this building, now that, was really captivating!!!
