It depends how much time is of value to you.
Loui1, my time is the second most valuable thing to me in the whole wide world, my fiancé being the first. I spent the first 20 or so years of my life being resentful, upset, lonely, and darn near got myself killed more times than I care to think of. I am awfully, painfully, horribly aware of the fact that at least more than a quarter of my life has passed by now. I am very careful about how I spend my time. Each moment of it is dearly precious.
Because of this, I refuse to fly. Not because I'm scared of planes. I'm not. I'd fly if there was a compelling need other than someone wanting me somewhere at their convenience more than mine. No, I refuse to fly because I can't think of a less pleasant experience. Considering economics, I can't think of less satisfaction for a dollar spent.
Think about it. You spend a considerable amount of money to fly. For this money, you stressfully race to the airport, get herded through an undignified "security" check that accomplishes very little, and race through a dingy, cold building to sit in a waiting area. Then you get to get in a long, rude line to board this small, smelly, noisy tin can.
Within this tin can, you can sit into a seat barely big enough for your tuchus, crushed against several other people. You are forced to listen to a pointless safety announcement- I doubt it has saved a single life. Then you can wait for your plane to take off, and when it does you get to enjoy the feeling of your ears screaming in pain. Then you may or may not get an astonishingly small bag of snack and a teeny can of soda from a plastic woman with a plastic smile who never even notices you. Then you can get more pain as the plane lands. I don't know about you, but it would take me a day to recover from this.
Me? I amble my way to my local commuter railroad road stop, get to the station a few hours early but only because I enjoy train stations, and sit in a first class lounge with free food and a usually friendly attendant- personally friendly. Then I board a train, am greeted by an often friendly and warm attendant, and some remember my face, even after a few years of not seeing them.
I settle into a comfortable room with my stuff. I go and eat real, delicious, and included meals, with other people with which I have a genuine, friendly conversation. I go to a lounge and enjoy the world going by. I drink some nice booze and talk to some nice people. I go to sleep in a comfortable bed. I wake up well rested, and eat a good breakfast. I arrive where I am going happy, refreshed, and comfortable. With NO stress. If I'm connecting and something goes wrong, I know Amtrak will take care of it. As they always have.
Because Amtrak is an anachronism that, more often then not, does the right thing the best that they can.
I have now enjoyed 20 hours of my life going from New York to Chicago rather than hating 6 of them.
Los Angeles to Chicago.... man, I cant imagine taking spending 48 hours in a sleeper.
Man, try it. Just once, give it a shot. You'll go no other way.
