Well, for me Summer is over. We had our first killing frost last night. Frost sensitive plants in the garden are gone. I picked the green tomatoes, onions and the summer squash. This event every year is the clear mark of summer being over for me. The official last frost free date in our zone is September 15. This year, like other years, we hope for a week or two more without frost but it seldom happens. With our record warm weather this summer I thought we had a good chance to extend the growing season but it seems not. Jack Frost showed up on time.

My grass this morning looked like this picture with frost on each blade.
There is lots of nice weather before Winter sets in. For many this is the nicest time of the years.
The leaves are changing. The air is crisp and cool. The nights are cool (good for sleeping) and the days are warm. (This afternoon it will be sunny and 17C ) The birds are on the move. The biting insects are disappearing. And for some, the hunting season will begin.
It will be early December before I feel Winter is getting a grip on us.
