I don't own a gas grill.
I've always been partial to cooking with charcoal and definitely like the flavor.
This article from Australia details the hazards that gas grills can sometimes present. With a gas grill, things can get out of hand pretty quickly.
For those using gas grills for cooking, exercise caution. Before firing up the grill, or any gas powered appliance whether it be a camp stove, turkey fryer, etc., it's wise to check for gas leaks. A little soapy water doused on the connections will help diagnose leaks quickly. If there is a leak, the soap will blow into bubbles and you should be able to detect the leak and repair the leak before attempting to cook with the grill.
