Put a camera out Saturday morning and was a little worried that the tank could dry up anytime. Put a chunk of salt a few feet from the mud. (Note the day is one day off on the cam, time is right)
I was thinking I might have to move the salt since we had a good rain that afternoon, so went to check it this morning.
What a difference! Need to go check a few more "dry" waterholes and see what they look like.
