Thats not what i meant. I meant that while the authorities would like us to stop plinking in our back gardens, i dont believe its enforceable due to it being orivate proprty. As long as the pellets do not leave the boundary and you are not causing a noise nuisance, its possibly a grey area open to misinterpretation just like the 'within 50m of a carriageway' legislation that is often debated.
No it will not be a reason to own, but i cant see them being able to stop you from doing what you want on private property.
