In my line of work I come across a lot of cool maps and mapping sites. This one I found posted on the anygeo blog. I thought it was especially relevant with our current economic problems and gas prices.The site lets you compare two vehicles and see how far each will go on just a single tank of gas. The map to the right is our two vehicles they are nearly identical. The mapping site can be found here. Don't all rush out and trade in your cars at once.
