Several years back, I was introduced to the weather rock. It worked quite simply.

If the rock is wet, it is raining.
If the rock is white, it is snowing.
If the rock casts a shadow, it is sunny.
You get the point.

It could not forecast the future, but was great for the obvious.

Jesus told the Pharisees and Sadducees they were able to state the obvious regarding the signs of the weather, but were blind to the signs from heaven.

Leaders need an eye for the obvious, but they also need a vision for the future. They must know the way and point people to it!
