It's Not Spring By a Long Shot

We've had some really nice days these last couple of weeks. Except for a little storm that produced slick roads with snow just barely covering the grass, this last while has been very pleasant with 40 degree sunny days and little wind.  Now this week, we are seeing a few days in the 50's.  I was outside this afternoon waving off some dear company and I noticed this:

My one lone spinach plant is still alive!!  I wonder if I put something over it in January and February it will live.  If it would I should be planting more seed now.
