Bring me home

Larry thought that he had the best way of getting around in the forest – he had read it an old book written by two brothers. Taking the remains of his breakfast sandwich, he left a trail of bread crumbs behind him to mark his trail. Naturally by mid-afternoon, he was hopelessly lost as the breadcrumbs he left behind mysteriously disappeared. While he had enjoyed the birdwatching that day (there seemed to be an unusually large number of birds gathering near him), there was no trail to be found! Those two “experts” were fakes. That’s the last time he’d trust anybody with the name like “grim”.

Right, he needed to get back to camp. He had a map … but which way to go?
