I live in North-central NJ and they literally wander down the middle of the road in herds.
Instead, this beneficial activity has been driven underground. We hear the deer being poached at night (when the poachers are using rifles). I imagine the more stealthy poachers are using crossbows.
Most poached deer where I am (Arkansas) are taken with small-caliber rifles - mostly .22 LR, but some .22 Mag and .17 HMR. They’re still loud but not nearly as loud as a centerfire rifle cartridge. They’re also generally extremely accurate and inexpensive.
