At 4 a.m. Thursday, six college chums huddled for warmth on a UW-Madison sidewalk just west of Bascom Hill, sharing three Badger blankets and arriving long before anyone else with the hope that later they?d see President Barack Obama close enough that, as Allison Berg of Chicago put it, “we could take a picture without having to zoom in.” Almost half a day later, at 3:40 p.m. Thursday, Obama took the stage not far from where they kept their predawn vigil.
