Jordan's Mom, you're a much better packer than me. I'd never get all that in a fanny pack. I use a small back pack which is easier on my back than the fanny pack seems to be.
Like BCVOwner2002, I carry a water bottle (sometimes 2 but not often), 2 rain ponchos and usually a ziploc bag of peanuts and sunflower seeds for the squirrels, ducks and other birds we run across. Sunglasses, and an all important eye glass repair kit. Last time I lost a screw out of my glasses and ended up having to leave the park to go to the on site gas station. My id cards, I keep in a waterproof cigarette holder around my neck.
