Deerzilla, I completely understand your position.  You were nice enough to allow me and my partner to shoot your property a few years ago.  We've lived and shot rats here since the early 70's, and have never disobeyed any landowner wishes, shot any pipes, cattle, sheep or off-limit rock chucks; to do so shuts that door right away, and only city fools would commit such transgressions with no intention of ever coming back.
Thank you for your previous hospitality.  I may call you again for permission, but will understand if you've "had enough" and deny us trespass privileges due to encounters such as you list above.
On a sidenote, the WX has been so wacky this season, the rats may get another pass....once for Covid, and now winter weather in spring.
