This site is one of the most helpful sites for outdoor cooking. I have read on here for a month and decided to just get a Weber OTG so I can still grill if needed. Well, here is my version of a hillbilly smokenator, hehe. I have been running on this same batch of coal for 5 hours and it has not dropped below 220. Side note...it has been windy and raining all day. These Webers really are something to write home about.
