Zack Wickett got slam dunked by the Maine high school basketball tournament. It was 7 a.m. Thursday, day three of the tournament, when a high school band, about 50 musicians, piled into Subway sandwich shop in Bangor. A closer at the Main Street store, the 20-year-old was the only worker on duty. “I was kind of frightened because I was not prepared,” Wickett said Saturday.
