If there's more than two of you in the group, neither do I...
In fact, it terrifies me to see client videos where the hunter has his muzzles pointed at the PH's back continuously while stumbling through the bush.
...and occasionally, to see a PH sweeping the cameraman while explaining something.
I was raised to treat every rifle as if it's loaded, and to never point the muzzle at anything I don't wish to kill. Perhaps the African bush demands greater risks?

Not wanting to hijack this interesting thread though, so that's definitely a discussion for another day.
