I once dropped my slide on the field, and it happened to be my first football game. it was 2 years ago (my freshman year) and the brass and woodwinds were meshing together and pulling apart and a sax player hit the back of my trombone and knocked my slide off. it took about 2 pages to get it back on. it sucked. also, later that same year, i was running across the field to get to a set and pulled a superman. my horn went flying and it skidded about 15 yards. i myself went about 5 yards. it hurt, but only a screw came out from my trigger and there was some scratches on my bone. i also (that same year, what horrible luck) fused my horn together by accidentally slamming it against the ground.
