If you are flying from a typical field then there is no store nearby. If thats the case bring at least 2 litres of something to drink such as pop, water, or maybe a coffee thermos. Its amazing how flying can turn a thirst on. Also bring a hat. The plane is up in the air and if you tilt the plane toward the sun you don't want to lose sight of the plane. A big brim aussie type hat works best because it will also keep the sun off your neck. The worst type is a baseball cap. You might also want to consider sun screen as this an outdoor in the sun type of hobby. Plan the trip so that you don't have to leave in a hurry. A first days visit can easily take up the whole morning. Its very annoying when you are trying to teach a new flyer and he keeps looking at his watch. Have fun! [8D]
