The horses at the beginning of a downpour with some thunder Part II - much closer together

I took the first video as we're loving the rain and there was also some lightning and I wanted to see how the horses were behaving.
Shortly after this there was a huge crack of lightning and the sound was immense. So I went back to take another video to see if there was more while filming. There wasn't more, but the horses had moved closer together.
Interesting to watch, that they move apart gradually with time after the threat has subsided. They do not react to distant thunder. Smart horses.

Interesting to see the blue sky, we're very lucky to be under the storm clouds.
