You just got a Fatbike and you wanna pack a Snow trail because you have know where to ride. You wanna get snowshoes.
May I suggest getting the MSR evo the price is right and they pack down the snow great and square out the trail. If you are solo snowshoeing like I do a bit myself, you will want to backtrack your trail alternating your steps to try to pack the trail evenly.
Also get some kind of sled or make one with about a 5lbs weight and drag it behind you. grab your favorite beverage and if your enjoy music grab you iMusic device.
