The Lord of the Rings films were shot on several locations. I think if I climb a hill near my house I can see Mount Owen which is allegedly one of the locations they used. Open tussock country with some decent beds of limestone. Never been up there myself, but I have seen similar country.
Yep... I have backed bows - two of them I think. I still have one of them and I gave the other away. I used one, made from introduced Elm, to shoot a goat. I used goat rawhide for backing, and I glued it down with home-made goatskin glue. I agree that backing adds some reliability and peace of mind... but I'd rather master the art of a simple bow carved from a sapling. Like you mentioned earlier... learn how to make a reliable bow so that you can have a formula to fall back on.
I have a very clever buddy who makes bows. Currently he seems to think that backing bows is the best way to go too.
One bow method I would like to try next is to get two strong saplings, each about a foot longer than one limb of a bow. I would then either overlap the thick ends and bind them together, or maybe make a long scarf joint and bind them together. I would then tiller the limbs... but theoretically if I had fairly identical saplings alot of the tiller would already exist because of the natural taper of the saplings. It wouldn't necessarily be a pretty bow, but as long as it delivered an arrow out to about 25 metres with a decent "smack" then really that is all that matters (provided that it doesn't break of course). This isn't an original idea... I think Tim Baker may have mentioned it somewhere... and I think I've seen pictures of bamboo bows made with a bound overlapped portion in the middle. The simplicity of the idea appeals to me... plus it is often easier to find two short straight saplings than it is to find one decent long one.
I don't pretend to know Canada's trapping laws, but I have an idea that the only thing you might be allowed to snare is a rabbit... and even then the wire size is specified (maybe this rule applies to only one region). Marc St Louis, a Canadian I believe, has posted a bit about this on the Paleoplanet forum. Snares are the way to go if you want some meat. Fortunately I don't think we have too many restrictive laws on the subject here....nevertheless I operate quietly without letting too many people know what I am up to. I have snared dozens of possums, a few rabbits, two wild cats and three pigs. I regret not taking it up seriously earlier in life when I had easy access to places where there was a fair bit of game around. Still.... I have many years left to play around.
Our possums were introduced from Australia... probably they are quite a bit different to yours. They are marsupials .... thus they carry their young in a pouch like a kangaroo.
Here are some pictures of animals I've snared. I'd like to stress at this point I am not a bloodthirsty "sportsman"... I just find it wonderfully satisfying to harvest my own meat using nature's tools.
