I dont need a pizza oven, but a fire place to the front of the rock closer to the picnic table could be nice. It would be neat with a closable side exhaust vent to run a removable pipe for cold smoking by closing the chimney and opening the vent, and running the pipe into the firebox on the smoker. That might get too crowded in my area though.
That would be a good one for you Wes. Drill a 3'' hole in the side of your fireplace and fire box. Add a threaded or slip fitting w\caps that would take the high heat when run as a smoker and fireplace. Install a pipe and close off the fireplace chimney when you need to cold smoke by burning a small handfull of coals.
