In all seriousness, you should be prepared for a few things that might come up... I would suggest putting together a kit with at least the basics, I would suggest:
- first aid kit
- jumper cables
- tow rope
- cell phone + charger or extra batteries
- flashlight
- warning triangle
- power bars or similar
- warm jacket/sweater + warm cap
- blanket
- flashlights
- extra water
- hose repair tape
- air compressor
- basic tool kit inc swiss army knife
- $100 cash + change
- quart of oil
- collapsible temporary gas container
- gloves (thick & latex)
- some large zip lok bags
- roll of toilet paper
- package of baby wipes

Woo-hoo! 3,000th post!
