Mbo, congratulations...Don't forget:1. Money, at least enough to pay your way in if there's a charge, eat, and fill your gas tank on the way back. (And if the crafts booths are good, you'll probably find something else to spend a bit on.)
2. A pen and notebook to write down stuff that strikes you along the way.
And if you possibly can, DO forget your "regular" life for one day, and have a great time!
