I've written both the state assembly person and state senator, and the congressman for my district, and both my Calif. senators, Boxer and Feinstein.
Made phone calls to them as well.
The result is pretty consistent. Either no response, or no help unless I can tell them specifically how they can help me without their doing any work.
My next step is to try to get a list of all the workers comp. people in my shoes. I figure their must be thousands left behind without any increase in their stipends for years. If I could get their names and addresses, get them organized, get them to write letters and make phone calls, then,,,,,
