In the Mts. its nice to know what is going on ! At Holloway Bar we have it all and its nice to have. Safety is number one and if there is a fire coming at you well that is nice to know to ! Glaza keeps a watchful eye on her gold miner and what is going on around him. I have live my life running on what I call timers, I time in and out threw out my day and if I did not time in there was some one looking for me ! 
I run like you would in a under ground mine, tag in tag out but there is some one that know just what your up to and where you are. If you can not work like this, then alone is and will be a dangerous place for you !
