Walking 12/31/2019, Part III

When I checked the weather map on my iPhone at 5:00 pm, it said the temperature outside was 72 degrees. Since that is still pretty warm, I decided to do one more walk before dinner. It was just getting dark and it certainly did not feel like 72 degrees but much cooler. Anyway, the track record said I walked 0.62 miles at a pace of 25’41”. On Google Maps, if you measure distance, my path comes out to 0.70 miles. That a fairly large discrepancy. I wonder if all the other walks have been measured incorrectly.
