I have no answers, but I sympathize. I’ve always wanted to ride a train across the country, but damn the prices are ridiculous. When I did make a cross-country trip a few years back (specifically so I could see the country and go through states I’d never been to before), I compared prices and decided to drive instead. The price of a train vs the price of fuel made the decision for me. Such a shame. But at least the road trip was worth it!
