True. I just see very few FS bikes amongst my circle of friends or at local races. In some spots fat bikes almost make the most sense, since we live on a giant sand dune and frequently have snow cover almost 5 months of the year (one friend actually has a Mukluk that she converts to a HT 29er for Summer). We don't really have rocks right in our immediate area. The people who have FS seem to be the ones who do a good deal of traveling to ride outside our close region.
