One of my favorite pictures of the tunnel. I am holding a bike rim and wearing a headlamp. My friend triggered the flash just behind my lower back. The fog is a temperature inversion at the entrance of the tunnel; it was 102 degrees outside of the tunnel and about 50 degrees inside, and humid.
I love that the administration building–almost 100 years old now–still carries the original name.
Near the guard post protecting the launch pad at the Duluth BOMARC is an orange windsock.
