Multimodal Tour of Arizona

My best friend from college, Diego, decided to have his bachelor party in Phoenix, so I turned it into the most complicated journey of my life; over three weeks I'll take the Amtrak from DC to Flagstaff, follow Route 66 and the Grand Canyon Connector to Phoenix, hike to the Supai Indian Reservation, party in Phoenix, then ride through Sedona back to Flagstaff where I'll catch the train home; wish me luck!!!
