A long time ago, my neighbor (across the street) told me about watering the lawn in the morning to give it a little 'drink'. So that's what I did this morning.
When I checked out the backyard, there was lump of manure-looking lump on the grass.
It seems that someone took their horse/goat and went inside my backyard and took a dump. (The consistency of the manure looked like a horse's.)
How could this happen? I live in a suburb. There are no horses or goats around here.
My theory is my next door threw the manure over.
