Bob Sherwin evaluated the road condition tonight and reported back to me that the road surface is mostly hard, except for the very top layer (about 1/8 in thick) of the westernmost segment (between the RR tracks and Silver Saddle). His evidence is that the road is not showing tire tracks, as it did a month ago after it rained.
Tomorrow morning, he is having a grader scoop up loose gravel from the ditches along this segment of road in order to redistribute it on the surface to ensure traction. The grader will probably arrive in the 8-9 am period, so please be very careful if you drive the road before then. Thanks.
