2. I find Amtrak a comfortable way to travel and sometimes fun when the train parallels routes you've otherwise cycled.
My first ever tour was ACA's unsupported Northern Tier tour. We started in Seattle and picked up the route around Mt. Vernon. I took Amtrak to the start. From Chicago to Seattle I had a sleeper. At the end of the ride the sleeping car attendant gave me a schedule to see if we could meet up one day at one of the stations. I did, in fact, get to see her in Havre during the train's break there. I tried a couple of other times along the route but couldn't make the timing work.
