How to keep these guys in my area?

What's the best way to keep these Big Boys in my area till Opening day in November?

I'd say just don't pressure em and scent protect and hope for the best . They should be good until the rut . Then you never know . Espicially hunting river bottoms . I usually shot a buck that I've never seen before ok camera

Good strong rope around the neck with plenty of food and water close buy. Remember though don't shoot the rope.

I'd say get a bow/crossbow, haha. Keep 'em fed, and as little pressure as possible.

High fence will do it

With that drop tine buck, I would go out and get a bow if I was you...

Water, alfalfa maybe?

Food, Females and pray for an early rut.
