Experimental garden

We have had a couple of hard frosts now and most everything has wilted including the marigolds and dahlias that brightened our front yard all summer. I covered one of the garden frames which includes a few lettuce and kale plants. the stick in the middle keeps rain from pooling over the frame. I am planning to add an additional layer of plastic before the average daytime temperature dips into the forties and we will see how well these plants fair a la Coleman-style. If they are still alive in mid-to-late January, I will declare victory and harvest them. Note that the kale and chard in unprotected frames three and six are still looking good in spite of the frosts.
