What a difference a few weeks can make. Just two months ago gas prices hit levels that had not been seen before after riding a wave of high crude oil prices throughout much of 2008 that crashed right into a nasty hurricane season.

Sadly, and somewhat surprisingly, I’m only talking about the album she released in 2005, but still. Before I start to feel any older, let me share some charts.
