Notes The short steep road connecting West Coald Creek Rd. and South 66th St. had almost a foot of snow and we could not go up it, so we had to backtrack and go up South 66th via Rte. 170.
We had our grandson's guitar recital at 4:30 PM, and because the prediction was for 50 mph wins at 1:00 p.m. and 70 mph winds at 2:00 p.m., so we started at sunrise to finish early.
