Hello! I recently purchased Ticket to Ride: Legends of the West and opened the box. It was clear that I was NOT to look at the POST OFFICE CARDS, and that the order of these cards is very important. However, while unwrapping the post office cards package, I dropped them and now most are out of order before I ever got to play! What order should they go in, and what would you recommend I do?
