The program in question? Denver’s bike-sharing program, B-Cycle. [Republican candidate for governor] Maes later told the Denver Post, “At first, I thought, ‘Gosh, public transportation, what’s wrong with that, and what’s wrong with people parking their cars and riding their bikes? And what’s wrong with incentives for green cars?’ But if you do your homework and research, you realize ICLEI is part of a greater strategy to rein in American cities under a United Nations treaty.”
