Here in San Diego we are struggling to get an 8 mile extension of an existing light rail line built that mostly runs along a Amtrak/freight right of way. This crucial project has been postponed and will not be completed until 2018. Meanwhile LA County passed Measure R and seems to have reaped an "InstaRailBoom."
For those of you not familiar with Measure R it is a half cent sales tax in the county that is funding all of the lines currently under construction there. To me this seems like a no brainer, why aren't other US cities copying the LA model on this one?
