There may be an underground light-rail subway in SF with three stops along its 1.7 mile route. It will probably end up costing a billion a mile. Couldn't we walk, and give that money to education and parks? Do that many people want to go to Chinatown? Do we want to tunnel 95 feet below the surface in a heavily congested area of earthquake country?
Would this be happening if our local Nancy Pelosi weren't Speaker of the House?
