Merced to Bakersfield is exactly right. Build it there first, figure out how to build it, fuckup where it's cheaper and gain the experience so when you have to tear up downtown LA and SF you know what the fuck you're doing and can get in, get it done right the first time, and then get out. No one wants to live in a construction zone, but it's worse when something goes wrong and the construction zone lasts 3x longer than it has to.
