Something you need to know.

Hi Nick,
Summer is in full gear, at least in the US. Anyhow, I'd like to share with you a little tip I got from a car mechanic last week. I have always wondered whether having the air condition on in the car or rolling the windows down was better. I mean which saved me gas? You might think that rolling down the windows would be cheaper, but that isn't the case. Whenever your driving above 40mph, it's better to roll the windows up and use the AC. This I because when the windows are open the air rushing in creates a drag that slows the car down, making you press the peddle harder and use more gas.
