Andre had some trouble with his passport being stolen and other
items at an AutoGrill (restaurant) on the way to Sigillo. Decided to take care
of the problems and not come to the Worlds. Gerolf dug himself a pretty deep
hole refusing to fly with any helmet other than his own. Decided not to
register.
