   A 5-foot drop in Lake Michigan water levels would widen beaches
   by about 100 feet, according to hydrologists at the U.S. Army 
   Corps of Engineers in Detroit...

Considering approximate total shoreline, in miles:

   Michigan   1,600
   Erie         870
   Huron      3,820
   Superior   2,800
   Ontario      720
              9,810 shoreline miles (much adjacent to Michigan)

At a width of 100 feet (let's save the bathymetric and geometric
subtleties for later), that means about 120,000 acres of "new land" to
come -- about 188 square miles -- the equivalent of five standard townships.

I think I asked most of the essential questions last summer:

I expect I'll need to send along reminders of these questions from time
to time, over the next decade or two...

     would be to acknowledge that the White House is full of them
