Not that early for us. Actually we normally have our killing freeze long before this then a few weeks of Indian summer before the first dusting of snow in early/mid October. Usually nothing serious until mid November, with the emphesis on USUALLY. I have an odd feeling all bets may be off this year. El Nino's tend to make our weather really crazy up here, right Alaskan?
Ahh, now I understand, wasn't sure where you lived.
