do too much of the work.

Ooops, I was so desperate to find a photo with a foot going in from the
back I failed to look at the hands. Both should be gripping the rungs
from behind to keep the trunk close to the ladder.

Unless the ladder's against a wall/rockface when it can't swing to leave
you hanging.
