Natural timing is the only time there is.
I think our clocks are going to really get a reset soon, and I don't mean daylight savings to standard. Autumn is when things are reaped and die, it's winter that buries and bakes. It's the autumn cycle and we can't neglect to take a look at the field to see what is out there. Without lamenting unplanted or neglected crops, we must reap or have it heaped upon us. Autumn is the most dramatic cycle of change.
