In a bid to get customers to buy more natural gas, William G. Wepfer and Melton Lancaster of the Arkansas Louisiana Gas Company redesign a charcoal grill to run on bottled propane. The resulting grills are pricier but easier to use and soon become the new backyard favorite. Gas grills come in two types.
 
Propane and Natural Gas.
 
When buying one make sure you know what your gas supply is going to be for the two gases burn differently. Propane or LP (liquid propane) needs more oxygen to burn, 25 to 1 oxygen to gas. Natural Gas only needs 10 to 1 oxygen to gas and also does not burn as hot as propane. I have a natural gas Weber Grill for I hate having to replace propane tanks.
 
Below are my favorite gas grills.
