Wear comfortable shoes and have layers available with your clothing. A fanny pack instead of a purse so you can pet all the fabric and toys.
Be careful: I wore out a 3 pair of socks because I loved walking all over ... except to the Fairgrounds [then we took the shuttle.]
We did carry granola bars and water bottles. After all I am from Arizona and don't go anywhere without a water bottle. Only now I take the itty bitty ones and refil them easily at water fountains or where ever I can. These also weigh much less.
