Preparing for the big freeze

Will it freeze or won't it?  We've been playing that game for the past few days.  The predicted Saturday morning freeze didn't happen, then Monday morning we had a light freeze that wasn't predicted.  Yesterday afternoon with predictions of a freeze headed our way I decided to go ahead and cover my most vulnerable plants.

The preparations are pretty simple.  With most of the container plants already stored in the garage we pull out old sheets purchased super cheap at the end of an estate sale.  You can see why they didn't sell early on.  The winds that blew in ahead of the cold front have died down so the sheets stay put. When the wind is blowing we have plenty of rocks available.  Sheets bring up the temperature just a few degrees but it's enough for most of our usually light freezes.
