My Uncle was a H.E. logistics guy for Guy F. Atkinson company that built dams and bridges all over the world who was in charge of getting all the H.E. on site and shipping or selling it off at the end of the job. My Dad retired as a E.O. Chief with the SeaBees working jobs from Alaska, Cuba, Okinawa, Guam, and 3 tours from DaNang everywhere down to Saigon. I used to enjoy as a kid listening to them try to one-up each others stories about shit that used to happen. Heavy Equipment operation is no joke
