My friend, the only way you will find peace within yourself is by hitting the sawdust trail at our meeting place over yonder.

2. dated Of an itinerant evangelist preacher, to begin travelling to the next location where one will preach. In this usage, "Sawdust Trail" is sometimes capitalized. Primarily heard in US. Old Bill Baxton? Shoot, he's been hitting the Sawdust Trail for the better part of his life. He probably wouldn't be able to settle down in one place if he tried!
