Take a two hour drive southeast from Atlanta to drive to the Warner Robins Air Force Base to visit an amazing, 51 acre aviation museum. It's free. It's big with four large buildings full of aircraft. It's beautifully done. Experience history lessons while pulling kids in with airplanes, helicopters, uniforms, weapons, and great educational displays. You won't be able to see it all in one day, so just start planning on your second trip.
