I lived in the area of the " booms" and they went off for the 12 years of it. I do think that a tunnel system extends to Denver and probably beyond- but also lived 24 years in Utah where we would see black unmarked helicopters flying up close to the bench of the mountain- always at dusk so hard to see if not looking. Not a doubt in my mind about a tunnel system there.
