Last chance

So this is it, according to my husband who was listening to the weather forecast this morning.  He called me from his car and told me to get the rest of the basil out, as tonight's temperature will plunge into the 30s and a frost has been predicted for Northeastern areas as far south as Connecticut.  Since he's in New York I guess that will be my job.  There's not much left in our plot but we have some in planters out back.  A friend of mine suggested drying it in the oven, but some believe that freezing it with a little oil will better preserve its flavor.
