Find it here: Draft SF to SJ Scoping Report (PDF). I haven't had a chance to look at this closely yet, but it apparently includes 950 letters from Peninsula NIMBYs - I love the way SFist described it:
The report includes over 950 letters from assorted cranky Peninsula NIMBYs, hippies, and Howard Jarvis looking Ayn Rand worshippers demanding that the high speed rail project be squashed underfoot like a pesky insect. That, or the rail authority should put the train in a tunnel all the way down the Peninsula from San Francisco to San Jose, because, you know, that would be like cost effective and practical and everything.
So, have a look at the document and post your thoughts in the comments. I'll have a fuller analysis on this either tonight or tomorrow.
