Yeah. And get to stand and watch them wander along their merry way, as there are so many people in the valley there, and on the sidehills, that the chances are, you'll never get a legal shot off. That, in the odd case that one of those barn raised animals actually manages to survive any length of time, with the realization that they likely only MAY have seen grass through the bars in the crate when they were moved from the Farrowing barn, into the weaner pens in a different barn.
Not to put too fine a point on it, but up here in Canada, it makes far more sense to know 'of' the pigs, and to be able to act appropriately 'if' you see one, than to put any real effort or hopes in to specifically targeting them, which, unless you have a smoking hot lead, is pretty much time wasted.
At least, that has been the pattern in Saskatchewan, Alberta, and here in BC, over the last 25+ years I have been following the issue.
