Cast Iron Gas & Charcoal BBQ are the most popular outdoor cooking appliance known to man. Nearly every family owns at least one barbecue grill, whether it is a gas grill, charcoal grill, electric grill, or portable grill. Most people store their grills on a back patio or by the garage for convenient use one or two times per week, with extra use during the summer months. We sure get a lot of use out of our BBQ grills.
