Housing sites are as listed on each corps's individual website calendar:
Phantom Regiment - High Point High School, MD
Bluecoats - C. H. Flowers High School, MD
Boston Crusaders -
Crossmen - Bowie High School, MD
Spirit - Crossland High School, MD
Jersey Surf - Central High School, MD
Btw I'm kind of a newbie to drum corps, is it okay if I just drive to one of these housing sites (specifically, Regiment), walk over to the stands, grab a seat and watch them rehearse?
