It is very short. You can read it in 60 seconds. Essentially it defunds the HSR Authority.
850,000 signatures are needed to put it on the November ballot. The signatures must be collected by June 1. There are no wealthy people backing this so there is no money for paid signature gatherers. Thus, qualifying the initiative will be a stretch and the failure to qualify will perversely be taken by supporters of HSR to mean that the public supports their position.
You can download the petition from:
Each sheet has room for four signatures. All four must be from the same county but if you have friends in different counties, download and print multiple sheets and use different sheets for different counties. You do not have to fill all the slots on a sheet. Mail completed sheets to the address on the web site. Signers must be registered to vote in California.
The best place to gather signatures is at farmer's markets. If someone has a card table and would like to set up at the downtown Palo Alto market on Saturday or the California Avenue market on Sunday, please let me know. I'm willing to sit with you and help and if it's cold I'll buy coffee.
