? for the rebreather divers

              Hey Doug! I've seen one that looks to run between Feigh and Pennington, 100' down (in Feigh) went into it a little, ya their real unstable, just like much of the steep banks of the Cuyuna, gotta be nuts to attempt that run. Theres a concrete tunnel in Portsmouth, just out and a little east from the beach area on the North side, with light gauge rail tracks on the bottom, thats pretty cool to see runs from 50' to about 30' going to the west, with a total length of about 100'. Seems once you take that iron out of the Cuyuna and mix it with 50 tons of cement, you can get a nice stable tunnel. I'd of been leary in those dug tunnels while the mines were active and "above" water, when you factor in the vibrations of heavy equipment, and blasting, YIKES! Gotta recommend to you Doug,,, stay out of the dug tunnels.    T
