Hmm, Interesting complaint.
Question for you. Who was there first, the fields or the housing development?
In Michigan we have what is called the "right to farm" act which basically says that if you move into a farming or agricultural area, don't bitch if you can't stand the smell of manure.
Interestingly, we have another law, patterned after the right to farm act that protects gun ranges and shooting clubs against encroachment.
Again - hey, if you move next to a shooting range, don't whine when the guns start banging away.
That said, crop dusting at night would be a pain in the ass. So- I do have some compassion for you, however, if the fields were there first, well,
With Real Estate, it is a BUYER BEWARE kinda situation. Maybe you should call your realtor every night when you are disturbed to share the love.
Of course, if you were there first, and then they started farming the fields, you have every right togo get in the farmer's face and demand satisfaction. Unfortuneately, the farm is probably owned by some huge nameless corportation, so in any case, your screwed. Sorry.
