Not sure we can come up with a full 50 experiments in "good" government.
CA is certainly struggling to come anywhere near that standard (and I'm not referring to gun rights or any thing like that, just good government.)
But knowing what doesn't work is often as important as knowing what does. I'm reminded of the story of when Edison was supposedly asked how he was doing on his efforts to invent an electric light bulb and he replied he had determined over 100 different materials that did not make a satisfactory filament for the bulbs.
Of course, the question is, what are the specific things in California that have lead them to their current state of problems? I might posit that a lack of respect for fundamental rights like RKBA and the right of parents to direct the education and upbringing of their children, coupled with the immoral desire to get something for nothing (as embodied in State run lotteries, encouraging illegal immigration so as to pay substandard wages, and attempting to tax another man to fund our desires) are at the real core of their problems. But somewhat more proximate might be issues of capping taxes (Prop 13) while letting expenditures not only run wild, but be dictated by popular vote. Indeed, the ease of citizen initiatives in California and their contributions to the problems there are strong indictment against pure democracy. Turning the social safety net into a hammock is another problem.
I don't know to what extent it contributes to or simply manifests the problems with California's government, but they have also proven that when everything is dangerous, nothing is dangerous (to paraphrase a line from "The Incredibles"). I can't seem to find a product, service, or even restaurant in California that doesn't contain substances "known to the State of California" to cause cancer or other serious ailments.
Certainly, some things California does are good. But if you're looking for ideas on good government, emulating the left coast may not be the best course of action.
