Carr entered CSM and joined the fraternity in 1987. Except for two years when the School hired an outside contractor to put on the display, he's been a part of every show. Even today, where everything is bigger and more spectacular than ever, the E-Days show is special. Its audience is small and close to the action so ground effects, which can't be used for large audiences because of their expense and low visibility, are included along with the aerial flares. Switching from ground effects to aerials gave us a chance to reload.
Fireworks come in a variety of types.
Salutes can be aerial or on the ground, as in the cannonade of ground salutes in the finale of each E-Days show. Within each type are subtypes. Pattern shells expand into a heart, a ring, an elephant or other shapes. Crossette shells spread out, then crack into four pieces near the end. Shell of shells break open, expand, then break open again.
