Savannah
When nine-year-old Savannah Walters of Florida heard about how driving on under-inflated tires in our country "squanders four million gallons of gas every day," she was determined to do something and adopted a catchy phrase, "Pump 'em Up." Now fifteen years old, Savannah goes door-to-door in her neighborhood with ninety-nine-cent tire gauges, and her volunteers have given away over ten thousand free tire gauges and shown thousands of adults how to get better fuel economy by putting the right amount of air in their tires. Savannah has also built a website (www.pumpemup.org), lobbyied Washington, spread her campaign nationwide to ten states, and been featured on NBC Nightly News with Brian Williams and as a CNN Hero.
