SUMMARY:A (Re) Introduction to the Milky Way (AAS Reprise)\, Astronomy
  Colloquium\, Bob Benjamin\, UW Whitewater
DESCRIPTION:If your picture of the Milky Way is that it consists of a 
 bulge\, disk\, and halo\, you might want to attend this talk. I will r
 eview the many recent advances in understanding the global structure o
 f our Galaxy\, with a principal emphasis on the disk and inner galaxy.
  Radio parallaxes to maser sources\, extinction distances to dark clou
 ds\, and large-scale near and mid-infrared mapping of red clump giants
  now allow us to map out different components (star formation\, gas\, 
 and old stars) of the Galaxy without the serious issues that plagued e
 arlier efforts. I will review some of the recent discoveries and direc
 tions for future work as I did at a plenary session at the American As
 tronomical Society meeting in Austin this January. After 60 years of e
 ffort\, I'd say we're about 50% done mapping the Milky Way.<br>
\n<br>
 
\nBut as a special only-in-Wisconsin add-on\, I will also show an int
 eresting (and in retrospect\, totally predictable) discovery I made wh
 ile preparing for this talk\, as well as showing some evidence that in
 dicates the resurgence in Galactic structure may yet hit some rocky ro
 ads ahead.<br>
