Interestingly about 50% of the miners wear the T shirts & shorts, the rest full overalls.
Had a trip down the North side yesterday, temp was reasonable around 34 deg, felt fine with the overalls on. The ventillation was good, I could still feel the incoming air right at the working face.
It was my first visit, thoroughly enjoyed it. Would well recommend it, if you get the chance, book a day off work. :thumbup:
The management thanks you for your co operation.
