The D Discount Pass
Got your sights set on Detroit? Good move. Metro Detroit is humming with so many things to do, that packing a ton of fun into a well-deserved escape will be a total cinch - especially if you use this section to sketch out your to-do list of events and attractions.
If you need a direct connection to Amtrak, make your way to the Weiser Railroad at Greenfield Village, one of a few heritage railways to have such a modern-day link.
