I played flute from 4th grade on (still do, hobby-like) and piccolo from 10th-12th grade for HS Marching Band. I was never hazed in my GLO, but my band camp days certainly had me ready for it. Did anyone mention drill downs and that magical fabric that band uniforms are made of, that provides little-to-no protection against the elements in winter and yet manages to absolutely COOK the wearer in warm weather?
