I was in San Antonio on business last month. The Arlington Yupette blog should be aware that almost the same battle is being waged there against a downtown streetcar line (at a projected cost of $280 million). Same entrenched Democratic machine committed to 'New Urbanism'. Same entrenched transportation bureaucracy. Same group of chamber of commerce and development-for-the-sake-of-development boosters. Same 'economic analysis' paid for by the City of San Antonio that 'proves' a streetcar line will generate $1.3 billion in economic benefits from development and redevelopment.
Difference between Arlington and San Antonio is that San Antonio residents are much more vocal and are collecting petition signatures to put a streetcar referendum question on the ballot in November. Same concerns about streetcar safety, traffic jams, and various costs to residents. So check it out on the Web.
