Who owns the air and sky between Langdon Street and Lake Mendota on the UW-Madison campus?
That question is delaying efforts by the UW Hillel Foundation to more than triple the size of its existing student center at 611 Langdon St.
The Jewish student organization, which traces its roots here to the 1920s and is the second oldest operating Hillel in the world, is seeking approval to tear down its existing 12,000 square-foot building and replace it with a four-story, 40,000 square-foot facility.
