In '95, on a windy Sunday afternoon, a LOT of us were waiting to take a once in a lifetime event to ride on a double-decker GO train through the tunnel. My brother and I and a bunch of us waiting all afternoon, were the last group to board on that train, to ride the tunnel and back (we had to wait a while, since other train traffic had to pass through the tunnel first when we were on the Port Huron side). An experience I'll never forget, as well as my face got windburned from waiting in the wind.
