How much do you want to carry?
Mick....I guess it just depends on how much weight you
are willing/able to carry on your back, and how long you
are going to be "out" and what you want to do while
you're out there.
A weekend hike is one thing, but a 2-3 week trek is quite
another....That's back-packing.
If I don't actually have to carry it on my back, then I'm
perfectly happy to pack whatever I want....but if the
weight of my pack is a consideration, then I'm perfectly
willing to forego all the shave gear!
You've been in the infantry...you know how much the
weight of your pack matters, right?
Frankly, at my age now, "roughing it" means having to
stay in a motel without a bar! :)
