Been an outside tech for going on 38 years now and plan on being here another 2 but a little advice to you young ones is in order. Would not recommend you stay in this line of work especially copper based part of it.
Work in NW area and there was a wave of hires going on about 2 years ago, they were needed then but we've lost so much business in the copper world to where the work isnt there. You young ones don't know it because you have nothing to compare it to. Group I work in can get along with half, the one across the way could get along with 2/3 of what they have.
