The Hatch Chile Festival is one of the better known fall harvest celebrations in New Mexico, where September seems to be the time of year when you start seeing chile roasters pop up seemingly everywhere, from grocery store parking lots to street corners. But that's not for no reason. Fall is chile season in New Mexico, and they take their chiles pretty seriously there, even as they celebrate them. During the green chile harvest, you'll see propane-powered chile roasters running almost around the clock. As the chiles roast, you can hear them pop and crackle. Most chile vendors and supermarkets offer roasting for a fee. For visitors, it's fun to tour New Mexico towns, such as Santa Fe, just to smell the aroma of the roasting chiles!
