Most school starts up on Monday. So maybe you're thinking about taking a road trip this weekend with the family. This wouldn't be a bad idea because gas prices are the lowest they've been since 2008. The website has maps from around the country showing you just how far you can go, and compares it to previous years.

The maps are assuming your car gets 24 miles per gallon, so make sure to adjust accordingly depending on what you drive. The website takes gas prices from 20 cities and takes an average. Back in June of 2005, the average gas price was $2.22 per gallon. In just three years it was almost double that at $4.15 per gallon.

But now, gas prices are back down to about $2.56 per gallon. If you live in Houston, or plan on taking a trip to Houston, fill up there. It's consistently the cheapest with gas prices coming in at just $2.12 per gallon.

So just in case you're looking for something to do this weekend before the kids head back to school, make sure you look into a road trip. It won't break the bank like it has over the past few years.
