I'd just bring enough dry/unspoiling food that preparation wasn't more than starting a fire, boiling water, and a few minutes of simmering.
Add the necessary pots, flask, lighter/firestarter, a decent knife or two, first aid stuff, and some form of survival guide.
A decent backpack, camp bed, a tent so I don't have to watch what Xen and Throb are up to.
A bunch of solar powered lights, insect repellent.
Maybe a GPS device to avoid getting too lost.
Definitely a huge stash of loo roll because the alternatives wouldn't be fun.
I can't decide if I'd bother bringing reading material, I think I'd prefer a sketchbook and assorted art materials.
And a couple of crash mats so I can do some climbing.
And some bagpipes. :)
