Being a railroad enthusiast (and probably a little OCD, besides) I just wanted to point out one minor detail on this absolutely amazing pic. The flanges on the handcar (hoofcar?) should only be on the inside of the wheels, not the outside. Other than that, I see no problems. The scenery is beautiful, detail is absolutely amazing.
And only Pinkie Pie would be able to have fun being stuck in the desert and doing manual labor to get home.
