Love the tunnel. I think that might have been ZZ Top instead of Brooks and Dunn. Of course, it could have been both since they did do it together. I also like that there weren't any ridiculous builds doing those trails. People around here have lost their minds building their Jeeps.
The Tunnel is on "Old Stage Road". You have to drive part of that road to get to the Trail.
The song is performed by Brooks & Dunn. It's from the "Sharp Dressed Men, Tribute to ZZ-Top" Album.
I typically like to tag along with groups of "Mildly Built" or mostly stock-Jeeps, as mine is my Daily-Driver.
It's plenty capable for most Trails here in CO though. I can run any of the "6" rated trails, and some of the lower-end "7" rated ones without any issue. (this, on a scale of 1-10 difficulty)
I'm not into the crazy-obstacles that some are. I'm all about the Gorgeous Forest-Trails, and the Amazing-Views!
