That's a great deal. Recently 5 of us priced out short trip to see friends from here to there on amtrak. we came up with around $400 round trip but all else looked good. we could drive it. And so $400 its tempting to just drive. Still we will probably try it once.
Way back up there somewhere on this thread, someone said my tax costs were $13 or maybe it $26 a year for amtrak. That's nothing. I spend that at chic-fil-a on any given saturday.
So, I'd easily support a 100% increase in my amtrak tax load and if the net effect were to depress prices on our little trip and similar ones for others by say "40%" -- we'd just about not consider driving it.
