Oh certainly the sod is rolled up and put somewhere behind a maintenance building. When I was in college, we found a baby robin that had been pushed out of the nest. Teaching her to peck for worms was a real chore; and especially it was a chore gathering enough worms for her.

Fortunately, we found the college turf farm, where sod was cut but not yet distributed to bare patches. To feed the robin, we would roll up sod squares and scoop up the worms -- nice, slender, tender worms.
