went to take some visitors thru the tunnel and found 2 issues. there is still ice inside, we went aprox 100 yards in from the Wickes side and started finding ice covering the ground. it was several inches thick. we backed out as we were running solo. we started back along the railroad grade and maybe a mile the grade is fenced and bermed, so turned around and back to the tunnel entrance area and back thru town. the grade was open last September when I was last there.
