I'll do a little testing on both as time allows. I won't be able to dig up the backyard, but if I can get out in the woods a bit with some time, I will work on the Dakota hole idea. Rocket stoves is just getting some bricks and some stove pipe and a garbage can. I'll get supplies on payday. I'll have to round up some wood as well. Maybe I can scrounge around the woods here. It's been raining heavily all day today, and things are pretty sopped, but I got a few dry sticks in the garage.
