At the rocket's launch birds scatter. Less from the rocket and more from the way the trainees are plowing through the undergrowth. Ah well, subtly is a completely different course.

Which means there are some folks going flat out when they come to the soggy bits. Some people just won't learn the easy way.

Not that all the teams are headed quite that way if the birds being startled are any indication. At least one team seems to think the rocket has been launched as part of a ploy to mislead.
