After working on perhaps hundreds of testing sites I lose track. Another benefit is that the testing company often travels to places it hasn't worked before. It might be good to know that "3 blocks over" someone else also once was required to test or not. I'm not sure the reciprocal of the work I might call it is kept track of, only the "location data" which is on a "need to know" and if I wanted as did Ezra Zubrow, Ph.D., summarize and compare the information, I would like to have more than the "volunteered" information on the NADB, which to me is insulting personally, having one work-site in Dayton, Ohio listed over Shaker burials for the Dayton Power and Light Co., back for 10 days of fieldwork the weekend Pete Rose hit his 5000 hit in his professional baseball career, as much as I liked the one motor many rope driven fans of the "Spaghetti Factory" there. Can't the SHPO keep track? Maybe not...in my state three different offices keep records. If they were taxi fares, dropped off at the road, and not "trespassed" with dangers and litigious backgrounds I wouldn't want to know, but as a GRE taking working stiff I'd like to at least to reference what I know with what I've done. One job I couldn't even get the name of the doctor who took blood and urine samples from its business manager. George Myers
