Having once been an environmental activist, one thing that bothers me about modern day environmental activists (*) is their insistence, despite any evidence, that jamming people into cities and going to Farmer's Markets and having governments buy huge swaths of land that can't be used by anyone is a good thing.   Emotional arguments mobilize zealots who are already convinced but do very little for the undecided.  But common sense and data do.

If most people were going to predict which city would instead have a common sense plan to get greener without more bloated government employment or a bigger deficit or laws, very few people would have said Detroit.

One great thing about being at a conference on a press pass is people want to buy you food. You can literally go the entire day without buying anything for yourself if that's how you roll. Breakfasts - check. Coffee - check. Lunch - well, I am not much of a lunch guy but I suppose I could get the proverbial free lunch in the way of a literal one. Dinner could at least be bar food.
