That is very cool that you got a picture of that.
We had that happen to us several years ago, but didn't have a camera handy.
They piled up like that and were at least waiste high, maybe a little higher, and circle about 10ft in diameter.
They looked like a hive of bees just climbing in and out of each other, and about the same size as those in your picture.
Kinda weird looking, but still fun to see.
Thanks for the pics, nice hogs and dogs,
Maver!ck
I was there......it was a cool sight!!!!!
