Yep, its late, but I had to get this list to the chief cartographer by today in order to get a geodatabase set up as soon as possible. Take a look and provide any comments if any come to mind. The list is somewhat stream of consciousness and may be missing a critical unit or may not reflect your conceptions. Let's work toward a consensus if needed.
