We turned onto N Colorado Ave and drove north. When you leave town, N Colorado Ave changes names to CO371. Continue following CO371 and you will find the tunnels. Thanks for watching!
It looks like the story begins north of Harrison and just south of what was the Shamar Ranch. Then you drove up to the top of the Pine Ridge and came to the stop sign right on the north end of Harrison. Then you drove through Harrison north to south. Is that correct? Thanks
