I dug up my blue potatoes today.  Digging potatoes is like gambling at a casino.  I get intermittent reinforcement. I dig and I don't get any potatoes.  I dig again and get a big fat one.  I try not to use the shovel. The potatoes didn't go very deep.  I have bad luck with the shovel.  I can slice 3 potatoes in half with one scoop.  I use my gloved fingers and rake the ground back and forth, back and forth until I see a splotch of blue.  Gold!  No, not gold, only potato but it is exciting to find one.  I find small button sized potatoes and others are a decent size. On my hands and knees I dig the soil and find my purple treasures.  I have a couple of pounds of potatoes which will be enough to serve purple potatoes at Thanksgiving.  Right now I have set them out in the garage to dry and cure for a day or two before I bring them into my lower level.  I'm sure they will be delicious in November.
