How economically accessible is interstate travel in US for average citizens?
You can take a Greyhound bus from Dallas to California for under $200. https://www.greyhound.com/en-us/bus-from-dallas-to-los-angel...
Note that's $200 each way. So $400.
And when I clicked the link, most tickets were showing as $250 - so $500 round trip not including lodging.
