I just finished a book (The Final Frontiersman by James Campbell), and there was a question that has been buggin the heck out of me. While hunting with the patriarch of a subsistence family in Alaska, Heimo Korth (said patriarch, and super-badass, my personal hero, god among men, etc.) tells the author that "you never shoot a moose unless you're sure the caribou aren't coming". Why is this? It doesnt get any further explaination, and I can't figure it. Does it scare them away? Is it a superstition? Or maybe he just likes caribou meat better? Anyone heard this or have any ideas?
