Another example. I can fly and land a real helicopter in my garden for 28 days a year, but I can only race cars around it for 14 days. Again not an invitation for a discussion on the rights and wrongs.
You can land a helicopter in your garden as much as you like, the 14 and 28 day rule applies only to land not within the house curtillage... However if you were to "race" helicopters around, that would be motor racing, so could only be done for 14 days, as would "paint ball games" which comes under war games?
