well as a stock photographer (we know all about model and property releases and how annoying it can be to be asked to provide a PR for a piece of artwork on the fridge created by your child....) I would clarify this remark and say "for commercial use". You can shoot anything you like from public property (depends on the country) and it's fine for editorial use, and fine for personal use. In many countries you don't need a PR for a house or other property like boats, livestock, equipment. I've also shot plenty of fashion stuff without a release, but it was all organised through an agency, and ultimately the terms of use fall on the client there, not me.I've been a pro photographer for many years photographing everything fro architecture to glamour and every thing in between. Bottom line is if you photograph anything belonging to some one else with out permission ( a model release) and you get pulled into court you will loose weather your on the ground or in the air, but you can legally fly anywhere that is not restricted air space. If states restrict airspace you have to adhere to it if it is FAA approved. There are some states that are passing laws that are in violation of FAA rule and with that your on your own as to which way to go
I've actually chased someone away from flying a drone over my farm, even though I do it myself. Why? because someone from the city doesn't understand that if you spook the cattle and they run through the fences they are putting their lives and property at risk, as well as the wellbeing of my animals and the fences. If there were animals around I'd side with the owner of the farm in that case. Also to reiterate what Horsefly wrote, living on a farm is a beautiful, peaceful way of life and part of that bliss is not being near any other humans.
