The writer, actor and radio producer wants to present readers with a unique view of history that he believes has not been explored.
Along the way, Schroeder has befriended other reenactors. Repeated conversations led Schroeder to conceive his own reenactment in his own neighborhood.
"You walk away from a military reenactment seeing the battle and gun smoke but never really grasping the history," Schroeder said. "You get the spectacle without understanding the content."
Schroeder chose the marathon-length walk in an attempt to "ambush" people with history.
"I'm not sure what people will find more peculiar — someone walking in Los Angeles or someone walking in Los Angeles while dressed as a Spanish friar," Schroeder said.
Among his friends who joined him along Glenoaks Boulevard on Saturday included a brother-and-sister pair he met when he participated in an 18th century boat ride called "The Big Row" down the Saint Lawrence River.
David and Reb Manthey received an e-mail from Schroeder in late December detailing his own reenactment endeavor, and they decided to fly out for the day.
"Our motto with 'The Big Row' is that anyone that wants to come play can come play," Reb said while keeping up with Schroeder's quick pace. "We figured if he could row with us, we could certainly walk with him."
The Mantheys were dressed in garb similar to what they believed would suit a Los Angeles-area resident in 1798.
Schroeder loved the quizzical looks from passing drivers and other pedestrians.
"People actually believe I'm part of a religious order, but then I start joking about how cold the back of my head is and how bad my feet are killing me," he said. "Once I get over that hump, they're fascinated by what I'm doing."
Although he was still gathering his thoughts after walking 19 miles of the journey, he knew the experience played an important role in his own life story.
"When people hear the word 'history,' they think 'cobwebs' or 'boring' and this has been anything but that," Schroeder said Sunday afternoon after nursing his sore body. "I've found a new passion in history, and now I'll start looking for a new adventure."
