Contact your politicians and potential politicians. It only takes a few minutes to follow up with each of these once you click on the individual's website. Call or e-mail (form letter below) or write or contact facebook pages for various politicians. If you call, be sure they take your full name and address. When using some politician's sites to e-mail, you will be asked to chose whether you 'support' or 'oppose' even if you have to leave the issue box blank because HSR is not listed. Be careful. If you support in concept, but are not 100% comfortable with the way things are, you should always check the 'oppose' box. From experience we know not all e-mails are read, but all are categorized and tracked. The same can be said for writing a letter. Do not start off a letter with "I support..." unless you are 100%, or else your letter will end up in the support pile. Always keep back up copies and send registered/read receipt whenever possible.
You should contact the your Senators, Congress members, Assembly members, the Governor and your city Council. If you do not know, find out who represents you in the Assembly, the Senate, and Congress using these links. At the local level visit your city's website and look under Council Members. Think outside the box. Contact potential political candidates that will support your point of view and let them know that you support them. Conversely, let those that do not stand up for your concerns know that you will not support them in the next election. Lastly, since the development of HSR within the United States is being driven from the top down, you should also send your message to the White House as they do not know the details of your situation, yet should be listening.
If you know your representatives or district already, you may find the contact information directly on this site.
Form Letter to Legislators. A form letter with e-mail addresses to the most critical contacts within legislation (according to State Senator Joe Simitian) can be found on the High Speed Boondoggle site here. CARRD also has contact information on their site here.
