 DW> But it also requires a large number of people who need to go from Point

I suppose, but _roads_ aren't profitable, so I'm not sure why trains have to be.

That said, there are reasons why the more-useful lines being built are along the East Coast and from SF to LA.

But that's long-distance. I tend to think that shorter-distance trains are generally more interesting, anyway. As I'm not going to commute on a daily basis from LA to SF, but going from San Jose to SF (or vice versa) is at least somewhat reasonable.

Yeah. Lack of density certainly makes the economics harder.

 DW> But there's still a question about cause and effect.  Did the extinction

I think there was some evidence that the change in CO2 levels came before the extinction events, but, yeah, if it's just two things at the same time, then, sure, harder to tell.

I'm not an expert in that part of the field, and have little interest in doing a deep fact check, here, at the moment.

*sigh*.

As usual, I regret engaging. My apologies to anyone I annoyed by engaging.
