He's better off rigging his entire property with motion activated night vision cameras.
The first thing I would do is get a hardwired security camera system that can run off a DVR and proper lighting around the property.
Beyond all the sharks with lasers & extreme guns which are already being covered, I’d focus just as much on a security camera situation that you can monitor, ideally from your computer & with an analog back up. Just make sure to cover blind spots, get as much coverage as you can. Get an easy monitoring system & back up. Having a generator is good practice in case electricity goes out due to sabotage or nature. It’ll all help you rest easier.
Regardless of feelings on the popo, make yourself known to them, talk to your lawyer maybe on the best way to do so, in order to get the best reception. Make it clear you are just a guy making a living doing what he do, & due to the nature of speech & current tribalism in the US, you receive a shit tonne of death threats. Let it be known to the police, state troopers, whatever law enforcement ends up having jurisdiction over your future abode, that you aren’t out to hurt anyone, you simply want to live your life doing what you do.
The troon menance & other faggots will be breaking laws, what you need to show is that you are living legal, protecting yourself, & thinking ahead of peace for your future self & community. Intent becomes important after incidents happen especially, though it’s always important to keep in mind how things will look and what will be provable. Cameras will be key, & physical evidence if (god forbid) anything ever does go down.
So, cameras, archives of trespassing, think about how long you’ll keep your nightly video footage. Some systems you can set for self erasing after 30 days, or other parameters.
Then, you have your guns & other security measures. Keep a good, loud shucking shotgun near your door. My motto is to avert trouble before it starts. Also, don’t forget to have plenty of side arms, pistols, revolvers, whatever your style is, after all the fancy shit.
I’d rethink swamp as well. Mountains & lakes are great, coastland is amazing if you can find a nice affordable pocket of it, without the hassles of idiot communities that tend to hog up the coasts. If you live waterfront, it offers a natural barrier on at least one side, which you still monitor, but it’s nice to have natural barriers. Rivers are nice, too. Swamps are underrated I guess, especially if you are looking at tough to cover terrain. Can’t help weighing that against quality of life & what would be the nicest though. It’s a matter of personal taste and weighing the pros & cons. Good luck.
