- Camera with film and extra batteries.
- Aspirin or favorite pain killer
- An Antihistamine, if you are subject to allergy attacks. Some shows are held in conjunction with real horse shows and the dust, horses, etc. can really stir up allergies and ruin the fun of the day if you aren't prepared.
- A snack. I like the fruit bits. Other good ideas are raisins, nuts, granola bars, cans of juice, etc. Avoid sugary stuff. You'll be able to get those anywhere, while things with a bit more staying power are harder to find.
