I love the White Tanks! 
It is one of the few parks in the valley that isn't completely surrounded by development, at the top are beautiful fields and you notice the fauna change. There is also water in huge white stone natural catchment areas, hence the name "White Tanks" 
However, recently there is a library being developed at the edge of this park, far from many homes and just plain uninspiring to think that everyone who goes there has to drive a good few miles just to read a book
Here are my thoughts on the matter that I wrote in this article about the new "Green" library in AZcentral
http://www.azcentral.com/community/westvalley/articles/2010/04/21/20100421-white-tank-mountain-regional-park-library.html

"I could not believe when I pulled up to the White Tanks to take a coveted hike through the beautiful hills, that the removal of huge cacti and the building of yet another public monstrosity was taking place. First of all how can anyone call this green? Can't we just leave one place in the valley free from so many cars, asphalt and brick? How is anyone supposed to get out there anyway? It is so far from most home development and completly in the wrong direction to support any kind of "Green" living and combining activities as most people do when they visit a public institution such as finding a place to eat lunch, a store to check out, or to mail a letter. Putting a library out away far from urban development and removing tons of cacti to transplant somewhere else is a crime against nature! "
