Clever Russians

[ogri48]

Good stuff mate. We just got back from our polish holiday, went to the salt mine where they have used the same method for hundreds of years to raise the rock salt out of the mine. We went 150 metres down and walked over a mile of tunnels and caverns, and yet only explored less than one percent of the mine. It's like a huge underground city. The mine accounted for one third of polands revenue. Clever them Slavs..
