I will be heading down to the world in December. I am curious to what you bring along with you. I don't want to be the one that forgets something stupid. I am planning on the following: 1. Laptop (Dump pictures) 2. Camera (XTi) 3. Lens (18-55) 4. Lens (70-300) 5. CF Cards (a variety) 6. Gorilla Pod 7. Speedlight (might be needed at MVMCP) 8. Battery Charger 9. Card reader I might pick up a Tamrac bag to use when I am going around the World (right now I use a Canon backpack). Would you suggest getting the battery grip and the extra battery???
