I remember a couple weeks back or so that you needed to dig some holes in frozen ground and you got some ideas.....

Well today I needed to access the inspection plate of the cesspool, of course the ground is frozen, with 8 " of snow covering...

So I cleared the spot, built a charcoal fire over it with about a third of a bag and covered it with a weber lid.....worked great, so in case you haven't done so yet, it works!, lol
