Hate to have to be the one to clue you in, 1rudeboy, but em2vn is right... this has been a problem in some areas also in Pennsylvania. When long-time residents have tried to get the cleanup of junk cars, rubbish, etc., from the yards of new Mexican residents, they couldn't get relief...yet the same statutes were being used against "anglos."
My former co-worker moved out of the house his wife's family had lived in for generations to get away from a similar situation, moving out of the neighborhood into a newly constructed place. (He was always railing against "McMansions" and new development, so but he found one that was modest.) Sure, it was a culture clash between a family that had been in America for 300 years and new immigrants, but I have to wonder if the new immigrants were in part trying to push out the old ones. It seemed more than just inconsiderate or uncaring.
Personally, I believe in property rights, and if the resident is minding his own business, then he shouldn't be hassled, whether it's about "unruly" grass or junk autos, but in any case, the enforcement should be equal, without fear of "ethnicity-bias" claims.
Maybe the Heritage Foundation or John Lott or some other reputable organization could do a study on, not whether people towards the bottom of the socio-economic scale have a greater tendency to have junked vehicles and tall grass in the front of their houses, but whether their immigration status determines whether they’ll be asked to clean it up.
