We have enough snow on the ground to warrant fat bike use right now, but also just enough that trying to ride a 29er would result in sliding out and crashing a lot.

Rode my rigid fat bike for 10 miles last night...With the lack of snow, a lot of the bumpy features that are usually under snow aren't buried right now...End up getting consistently getting busted in the balls by the seat. That gets old and reminds me why I don't ride rigid when I don't have to. Full suspension for the win.
