I didn't think this kind of flying existed any more in the UK!
It does to a certain degree, being friendly to the folks you meet on your travels helps , knowing other farmers offers more fields and areas for landing even if it's just for 5 minutes for a pee and a smoke, and if all else fails be stealthy.
Edit to add; most landowners in remote areas are usually more gob smacked that an aircraft could or would land in a field more than they are humped off about an brief unannounced visit.
