Close, but No Frost

Here we are in mid-October and we've yet to have a frost. In the Adirondacks (South of here) the fall color is pretty much over, most of the leaves are down. Our foliage is just peaking and leaves are falling at in increasing rate but the geraniums in the window box and the impatiens in the planters are still in full bloom. In years past we could expect a killing frost any time after Labor Day. This year we have summer flowers and autumn leaves side by side.
