Nice, I have still yet to venture under my house, I know there is an underground to this house! If it's anything significant rather than a 2ft by 2ft space I may do another vid, if I can get in without being electrocuted that is.
I had a proper look today, right cowboy doing the wiring down there. No chance am I going down there, its a pity there appears to be several chambers under the house, and standing height in places by the looks of it. A few artefacts I could see too.
