This summer on my trip I read "$20 a Gallon" by Chris Steiner. I rate it a 4 on a 1 - 5 rating. The book is what will happen "when" gas hits different prices, each chapter is the dollar equivilent to the price, chapter 7 is what will happen when Gas hit's $7 a gallon. He did lots of research and I recommend the book. One thing I read was that at $18 a gallon Walmart and big box stores go away, we will return to "mom and pop" shops and buy more local.

Now I am reading (ok, I am cheating and listening to the audio book" of Dan Brown's "The Lost Symbol" I just started it but will let you know what I think when I am done.
