'Tis a blast. I call it my monster truck. I also have a full carbon fiber 6" travel dual suspension mountain bike with Fox remote reservoir shocks that I call my "Raptor" (after the pickup, with similar suspension tech). It absolutely crushes dry trails. But I think I have more fun going slow on the fat bike in the mud & snow. Great exercise for both myself & the dog. The dog definitely prefers the fast bike though
Mountain biking in general is what converted me from 1911s and SFA pistols for AIWB carry. I enjoy the fact my P30SK has a 10lb DA trigger pull (I have a decocking LEM ), a hammer block and TWO firing pin blocks in the slide while I'm flinging myself down steep single track.
It's also the reason I evangelize for a single stack p30/p2000 at every opportunity lol
