I know a way to help California, get rid of all the Frickin illegals putting extra strain on the water resources. Because much of California is a desert it goes through feast or famine as far as rain, if instead of wasting billions on the bullet train from nowhere anyone wants to be, to nowhere anyone wants to go, it was spent on reservoirs to store the rain when it does fall, and desalination plants(denied by water resource board members who know nothing about water resources, California may not be in such a dire straight.
