On Friday, May 20, I will fly from Washington, D.C. to Los Angeles. In L.A., I will board an Amtrak train bound for Orlando. From Orlando, I will take an Amtrak train back to D.C. , arriving on Wednesday, May 25. I will attempt to document my six-day trip using a laptop computer with a wireless Internet connection, a GPS tracking program, a hand-held radio scanner and a digital camera.
