I learned years ago from the legendary SUN BEAR to watch the ANTS. He also taught me how to use a ROACH in a jar to warn of impending EARTHQUAKES!
So I have been watching the ANTS here in my little western North Carolina mountains town building the HIGHEST hills I have ever seen! They are going WAY DEEP!
Sun Bear said that the higher the hill the COLDER it will be!
Yes, I predict they are preparing to SURVIVE the current Grand Solar Minimum!
