I would ask the event people if they kept the box that the egg came in and dismantle the egg. Make certain to tie-wrap the spring loaded hinge prior to loosening the bolts and removing the band, Rember how all the pieces fit in to the egg while disassembling it. Place all the pieces in the boxes and place in the back of a pick-up truck. Securely tie down the boxes and drive home.
Reverse this procedure once you get back to your house. Keep the spring loaded band tied until you completely assemble the egg. Good luck with your first cook-out.
