Interviews with the perp's acquaintances and employer suggested that he was a normal-appearing person prior to him doing this.
As for Amtrak, I know its not considered Freeperly, but I love the train. I dont fly, and its much more comfortable for long trips than the car. I have been sorely disappointed that they have never opened the southern route since Katrina, as I would love to use it to travel from S. FL to TX to visit my kids (and even to NM to visit my elderly Dad). As it is, we try to drive back once a year, which is all the time my husband can manage from his job since the drive itself takes about a week (round trip).
Train travel does indeed have a great charm and can be quite comfortable. I consider it most "Freeperly" to let people travel in whatever way they want without being made to feel guilty about their choice :-)
(yes, I'm waiting for jetpacks to become perfected and less expensive)
Jet packs might be fun! ;)
