RE: Backpack Hunting
That is pretty much most of what we do here in New Zealand.
My best advice is get a good pack that fits properly.
Light gear is a bonus and certainly makes life easier, but it is not essential, its the sort of thing you build up over time.
This sort of hunting is what I really love, a total break, it refreshes your body, mind and soul.
Find a buddy and get out there you won't regret it!
