MILWAUKEE ASTRONOMICAL SOCIETY
The Milwaukee Astronomical Society has a respectable antiquity, dating back to 1932. Among its early members were none other than Walter Scott Houston and Ed Halbach. MAS members are loyal, many retain their membership even when they move out of state. We even have members living in Colorado and Arizona!
