We think that it may be recycling water bottles. You may have to sort items between trash and recycling. Triangles have appeared a lot, and the symbol for recycling is the triangle. The water bottles were arranged in a triangle. The coordinates from the original numbers led us to Rockford, IL and Colchester, IL, which have metal recycling facilities. Blue and green have appeared often, which are the colors for recycling.
