Loved the "spec worksheets"...nice to have a catalog to search out solutions....spec p41 "preload manned and planned to complete sort 1/2 hour to driver start". I was also good at pro-rated mar's and profiles. I had my own red and black pens. Had all this in a binder. Kept it on a shelf next to the JBA's, Sphere's of Influence, Policy Book..etc. Are we living in the past? Looking back it all seems alot easier, doing without technology.
