It's one of my favorite TV series. I agree that an 8 month winter isn't appealing, but I would love to spend a summer fishing up there. It is the only state that I haven't visited yet. On my bucket list for sure.
Between Alaska The Last Frontier and Yukon Men, one thing I've concluded is that I couldn't risk a subsistence lifestyle in such a harsh environment. You could survive when you have the stamina from youth and middle-aged, but what do you do when you get really old? Unless you have children to help out, you probably just die.
