So far, two! Not sure it is done, but I remain hopeful. I have just come in from walking the dogs, in a heavy coat, a felt hat, and cotton gloves. True I am not wearing my winter coat, or my lined gloves, or a wool muffler. But I could. My feet are cold, the sun in absent, and my hot tea tastes great. I just finished the cruelest April I can remember in a long time, don't make May be cruel. It is all in how you view it? I am working on a attitude adjustment, some sunshine, and a rise in the temperature.
