I'm a little confused by your statements username.
You support better public transportation.
That means you recognize that public transportation reduces traffic, and emissions, etc. from less people driving.
You support a cleaner environment.
And champion places like Flushing Meadows, because they offer places to play.
(Albeit suggesting a 2 mile walk there is feasbile for young children, especially after playing on the way home).
You support walking as a form of exercise.
But are concerned the about the lack of parking one street causes?
Here's what I think would be an ideal project for you based on that ...
It obviously makes sense that since children can't walk as far or fast as adults, the park needs to be closer to the communities, but I like that you advocate those 2 miles walks. By your thinking, improving the air quality of the whole neighborhood would be to build a parking lot 2 miles away that EVERYONE who drives a car could walk to. If you have kids, you can drive by the neighborhood on one designated block to pick them up after you get your car. Oh wait that makes no sense ... yes Iw as being sarcastic, forgive me ...
Hmmm ... better to stick with the plan in place. A little room to play for the kids, at best 20 cars affected. Seems fair.
