Mission Details
It's not hard to figure this one out. Take the position of driver on the stage coach and drive Bonnie to Armadillo, following the route on your map. Don't exhaust the horses, or you will be riding a lot slower than what you can. Staying on the road will make it a faster and smoother ride.
