Fire the pit up hot - over 300* and use bacon grease to season the interior grates (like a cast iron skillet).
Keep the pit at temp for a few hours. Some use PAM spray or canola - a high temp oil.
Lang suggest closing upper damper to "smoke cure" the grates for a couple hours.
I also coat the exterior for some weather protection... allowing the grease to bake on.
Bacon should be capitalized as a pronoun for pork!
