Frost?

Perhaps.  

Duckweed floating down WW creek.

Locust leaves falling on the ground.

Patches of frost were sighted in Starin Park this morning, but the resident rosemary, under the redbud on the back patio, felt no ill effects.

The average annual frost date for this part of Wisconsin is October 15, so we are pretty much on schedule. And when or if the thermometer reaches 70 degrees after a frost, it's Indian summer. There is almost nothing nicer than Indian summer.
