I really don't think I am going to get one, because it just doesn't snow consistently enough here, and the ones I want (Trek or Specialized WSD), that will fit me are not cheap. I will probably try it at a nordic center this year. When it snows, I want to be x country skiing. Plus, if I was fat biking around here, I'd be on fairly difficult trails. I cannot see putting fat bikes on the rack, to drive 2-4 hrs. to get up north, or to western MA. Does this make sense? Given my poor experience with mountain biking, I think getting something else for my 3d bike would be better.
What that will be, I don't know. It's pretty much between a gravel/dirt road bike, a city type bike, or a cheap mountain bike to do both of those.
Northwoods, I used to use snow shoes to go out on hard packed trails with just a couple of inches of snow. It did seem like overkill!
