may I add that it is not just better urban planning that is needed, but a whole education in cluster development, open space preservation and well thought out infrastucture placement.
They now have college courses that use the building practices of the 1950s & '60s to illustrate what not to do. Better late than never, I guess. But these are not the folks who end up on town planning boards.
This thread is starting to look a lot like the issues that my job has to deal with... lol.
