You don't exactly get into the Mine, you need to go to the Mine Shack (make sure you have cracked the code and it tells you to go to the Mine Shack) and go left to go in a corn field. You complete this corn maze by following the fallen popcorn. When you start to see paw prints, you will see them on both sides. Go right from there first and follow the paw prints (pick up the pieces of paper on the path). Then you will come to a dead-end to pick up a plank and the last piece of paper. Then go left and follow the flipper prints (this is how you go back) and keep following it until you see a pile of popcorn. Go right and you will see that you have come here before, this is where you took a right from. Now you take a left and follow the paw prints again till you end at a river to use the plank to cross it. Make sure you picked up some corn from the gift shop while beginning the mission. You throw that corn into the fire to bring the ladder down. You will see Herbert talking. When he stops talking and keeps laughing, plug his computer out and the broadcast will be stopped.
