No consideration

Today I went outside to an area on the back side of our shed which we only use for a compost area. So I dont go out that often to this area. Only to find that the people who clean up the vacant house behind us dump their garbage their. This is so fustrating as the sheriff said I cant prove it so I have to pay to have it dumped. I say I know it was them because it is in an area only they could reach so obviously they felt we didnt go back there and wouldn't notice until it was to late. I really think this stinks but I guess I cant do anything about it but vent and figuer out a way so they cant dump anything else over our fence in that area.
