[DF] 40 Days Travel Time?

[RyanW]

One thing overlooked so far is the farrier and his kit. If you're taking horses, and the trip is 80 days total (40 there, 40 back), you should really plan on reshoeing the horses just to deal with normal hoof growth. Plus any damage that requires an "unscheduled" reshoe.

If it's 40 total (20 each way), you probably still need one to handle damage, but if the horses had fresh shoes when you set out, they might be okay for the trip.
