Throughout 19th century Americans migrated west to settle land and most such trips were on foot and on covered wagons. With the arrival of trains the wagons stopped, but my guess is that not everyone stopped using the wagons right away, since it would be expensive to take all your belongings on a train.
I would like to know when people stopped using covered wagons all together. Did people suddenly stop using wagons as soon as trains arrived and if not how long did it take and what finally persuaded everyone to stop using the wagons. Also of interest would be to know when the last caravan using covered wagons left for the west.
