I just saw a great site if you are planning a road trip.  www.gasbuddy.com lets you check gas prices all over the US so you can plan where to stop for the best prices.  You can drill down by state and city and it actually tells you the prices for gas stations in the area.  Here is your chance to use that new iPhone. 

It's a great tool for everyday use too.  I've added a button on the SideBar...just click and it takes you to the Miami version of GasBuddy.  It will show you ranges with the ability to filter by city (on the right).  Broward cities are included in the pull downs.
