Ann Arbor, Mich. -- The Old IM Building at the University of Michigan had its 75th birthday on Oct. 18, 2003.

The 14 courts in the venerable, old structure saw some of the finest paddleballers sprint around during a half-dozen National Championships over the years.

Properly called the Intramural Sports Building (IMSB), it was the forerunner of all campus recreational centers in the country.

It is at 606 E. Hoover St.

It was the dream of Dr. Elmer B. Mitchell, the building's principal planner, that it "would provide a place where a thousand students can enter daily to congregate and to mix their exercise with sociability."

Work is under way for much remodeling, including a weight room, a climbing wall, new locker facilities, a very modern front entry desk and other features.
