Remember to have this.

• Food 1 pound per day (each 2 pound ration only gives 1 pound of food because D&D is a harsh mistress)
• Water 2 gallons per day
• Bedrolls 1 per person
• Tents (one tent fits 2 people)
• Insect repellant if you so wish

If you have animals they need food and water but not the other three things.
