The Madison Scouts drum and bugle corps, one of the Drum Corps International's world class performing units, is returning to East Troy for the conclusion of their annual spring training.  Each year the Scouts develop a 10-minute field production that they will perform through-out North America on a circuit that will have them competing in 33 shows starting June 19 in Rockford, ILL and concluding on Aug. 9 at the DCI World Championships at Lucas Oil Field in Indianapolis, Ind.  The Scouts will be rehearsing and welcome the community to come watch the daily rehearsals, as well as a full dress rehearsal on Wednesday, June 17 at 7:30 p.m.  They will also perform on July 5 during the East Troy Lions Club 4th of July parade.
