Round 1: I planted, covered, watered, and mulched a sarvicetree and a purple juneberry along the fence.
I also saw a green tiger beetle. These are voracious insectivores and pretty to watch. Just don't touch them because they have savage jaws and chemical defenses.
EDIT 5/29/17: Round 2, we picked up a mound of raked grass. This completes the ritual meadow. \o/
EDIT 5/29/17: Round 3, we picked up sticks in the yard near the house, moving back to the east edge.
