I'd agree with that.... A dig needs a face, or a bottom. I suppose you could work by project in a complex system. I reckon open passage between dig faces in the same project constitute part of the digPie Muncher said:OK, my omission, should maybe have said longest continuous dig. If you no longer have to dig to get on, it's not a dig anymore If the way on is blocked or you can't get through, it's a dig, yes?
