just a few 1) What are some methods to starting the fire? 2) It seems that one draw back to the UDS is adding wood to your fire. How is this done? 3) The barrels I bought have the flat lid. They have a hole with threads where the cap is at. Does this hole work fine for an exhaust or do you get any enhancement from adding a smoke stack? I had other questions but searched the forums and the answers them and this is all I have left. Thanks in advance.
