Thanks for the info. I will follow up, any more help would be appreciated...
as far as housing, this first project is six months or so....I have family in Helena area I will stay with for short term.
Kids will all be in Bozeman for next 5 or six years getting various degrees.... so looking for house there, wife can stay there and will be our home base....
once this project is done wife and I will likely follow the work around the country...maybe end up with nice big fifth wheel and live like that for next decade, we enjoy traveling....so six to ten month project could make life interesting, while traveling and getting to know places and people everywhere...
Kids really like Bozeman, a couple of them might stay forever, if they can get good jobs. we like the area also. Lots to do in area.
