Being a Pony Express rider 150 years ago wasn't easy.
Riders changed horses every 10 to 15 miles.
But the riders themselves only changed every 75 to 100 miles in what might be compared to a relay race.
Riders faced many dangers such as buffalo stampedes. They faced robbers who wanted to take the money and jewels sent in the mail, said Megan Roach, museum store and admissions manager for the Pony Express Museum in St. Joseph, Mo.
Some riders died.
The riders rode through all sorts of weather - rain, sleet, snow and hail.
Roach estimates there were 80 to 100 riders. The youngest was 11-year-old Bronco Charlie Miller.
And sending something via Pony Express wasn't cheap.
Back then, it cost $5 to mail an ounce, Roach said.
