Luggage and bags:
Don't forget to bring your pets with you if you enjoy traveling with them. Timber Loft is pet friendly.
Clothing/Shoes/Weather Gear: You may need a heavy coat if you are there in the Winter. Most people don't think of Georgia as a cold place, but they can have some very cold nights.
Photo Equipment: In addition to the normal insect repellant, sunscreen, etc., I suggest, especially if you are traveling with children, that you invest in some cameras for them. I bought a waterproof one time use camera for my grandson to take tubing and he loved it. It was about $15. Also, I bought a one time use digital video camera which gave him a souviner of the trip of his own making. I had a ball watching him video and listening to his young commentary. At one point while filming at Anna Ruby, he annonced, "It is quite nice here. Have a look around," panning a little to fast but not too badly. Then he pointed the camera at me and asked, "What do you think?" The video camera was about $30 plus about $10 for processing - still a great thing for him to take home with pride.
