bread trail fail

This morning on my walk to school, I saw a bread trail. no, not a bread crumb trail, because the pieces of bread were each about the size of my hand. I'm really curious as to why somebody would leave a trail of bread (I'm pretty sure there's no Hanzel and Gretel in Minnesota) , and why, if they are making a trail, why they would make the pieces of bread so big... the trail wasn't very long.
