Also, I recently rode on Amtrak for a long trip from Columbia, SC to Baltimore, MD. This was my first time on any kind of train other than a subway or metro line. It had its drawbacks (incredibly long travel time and delays)

I thought about taking an Amtrak to Boston for a trip since it was a vacation and I wasn't in a huge rush travel wise. By "incredibly long travel time" in my case it would have gone from ~3 hours (two roughly one hour flights with a very short layover you've got to haul ass through because for some reason the relevant gates are both at the far ends of different concourses at Dulles) to about a day. Wasn't in a rush, but that's a bit too far to the other extreme.
