I teach my students to call before engine start to get their clearance
(controlled fields). You are allowed to call up to two hours before your
proposed departure, so why waste your gas waiting for the clearance to be
issued?


Allowed by whom? The strip doesn't print until 30 minutes prior to the
proposed departure time.
