RE:RE:RE:napkin numbersWould not surprise me that GEO ( if still following) would know the answer to that in a bit of detail but I suspect yes they are well under some city streets and local lakes close to the mine .....on a quiet night when the air blower system at con was not humming one could hear and in odd occasion, I swear, feel the rattle of them working deep underground...so again this would not surprise me.
I don't think with our rock, we have to worry about sink hoes either lol
