Wow...where to start? What unit are you hunting? Do you have an outfitter lined up? If you are planning to hunt on designated wilderness and there is a lot around Dubois, you will need an outfitter or hunt with a resident of Wyoming. Do you have experience hunting elk? Are you backpacking in, using horses, etc? The game population in the areas surrounding Yellowstone is a shadow of what it once was due to the wolf reintroduction.
