So I was thinking about what it was like working for the Pony Express and I am wondering was it an extremely dangerous job? I'm thinking that given the success of the Pony Express it must not have been extremely dangerous (otherwise people wouldn't have done it) but I am struggling to find good sources to confirm this suspicion.
By "Extremely Dangerous" I would say there was a good chance you wouldn't survive a year or something, say 1/5 died. I mean would you have to have been a crazy person to work for them. This is kind of the evidence I am looking for. High attrition rates from injury/death, etc.
