>>771535I had planned on picking up a pair of second hand gum boots on the way to the mine this morning but I left too early and none of the stores were open. I ended up hauling a long 2x6 into the mine, floating it down the tunnel, propping it up on rocks, walking the length of the plank, balancing on any large rocks nearby, floating the 2x6 further down the tunnel, and so on until the tunnel banked upward out of the water.
