*a sturdy pair of hiking boots. My feet are tender, despite being hobbit-like. So this is obvious.
*one of those rubber ball/paddle combinations with the rubber band. It's important to keep your mind supple, and thinking of ways to continually repair the broken rubber band is sure to provide hours of entertainment.
*a device to filter water. I'm pretty openminded, but I don't want to go straight bear grylls. Pee is unsanitary. It doesn't appeal to me.
*a good knife. Mostly for whittling things. Potentially for buttering toast in a very dangerous manner.
*a loincloth. Satin and interestingly embroidered. Preferably with dragons, possibly flames. Maybe throw some sequins on it.
*a nice thick towel. Like the ones your mom keeps for guests. No galactic hitchhiker should ever be without their towel.
