Some cold hard facts about adventuring with your camera:
1. If you are prepared for animal sighting, and remember to leave your telephoto lens on camera, you will not see ANY animals at all. Not even a squirrel.
2. If you are prepared for great landscape opportunities, and leave your wide angle lens on camera, the light will be either be completely boring or way too harsh, but you will see a lot of really cool animals that are far away.
3. If you dare to stop and eat dinner, the service will be horribly slow and you will leave the restaurant just as the amazing light is fading.
4. If your battery dies, you are guaranteed to see a majestic grizzly bear ninja kick a wolf in the midst of a wonderful landscape in the best light of your life, and nobody will believe you.
