In addition to the various towns that boast of their white squirrel populations, a number of university campuses in North America have white squirrels. The University of Texas at Austin is home to a white squirrel population which has spurred the myth of the albino squirrel as a good luck charm. There are many versions of the tale; one of the more popular versions is if one spots the albino squirrel before an exam, they will ace it. The University of North Texas founded the Albino Squirrel Preservation Society in 2001, which has since acquired several "worldwide" chapters. In 2006, the University of North Texas held a student referendum to name their white squirrel as the university's secondary mascot, but the vote was narrowly defeated by the student body. University of Wisconsin - Eau Claire has a significant white squirrel population both on the campus and in other areas of the city of Eau Claire. Michigan Technological University in Houghton, Michigan is home to frequently sighted white squirrels that live on and around the campus. A Facebook group dedicated to these squirrels, called "I've Seen the Albino Squirrel of Michigan Tech", was created for people to post photographs and anecdotes of their encounters with the white squirrels, and includes some stories from Michigan Tech alumni that recall seeing white squirrels in Houghton dating back to the 1930s.
