I think some of us, particularly Baby Boomers, would love to have a time machine. There are those eras that we would jump at the chance to spend a few hours, days or even longer in. For me the 1930s has always been intriguing. While it was The Great Depression, there was the great era of streamlining. Especially in the railroad world.
To think of the amount of trains running on any given day seems like it would be a continuous railman trip.
Putting aside the social norms of those times and having the knowledge i have now, I think it would be a very educational adventure.
