In a previous post, I asked if another person was familiar with Brad Potts' ATWOOD data Website. Since then, I have been asked for the URL. Here it is so that the whole list will know about it. It is the most useful source of ATWOOD data that I know of. http://homepages.rootsweb.com/~genesis/atwood.htm Enjoy, Allen E. Humphries Saugus, MA USA
