Just below 30 F when I left this morning. I had to hit the doctors for a physical before work. There are a couple of nasty hills which were not much of a treat for my 70 lb Mango. I mashed my way up them and had a pretty high pulse when they checked me. They called me right into the office, so I did not have any time to cool down or rest. Despite this, by Doc said I was in great shape. 43 years and counting.
