During America's early years our land was filled with evangelism.  It's no wonder there is a Methodist and Congregational Church in nearly every town in New England today.  Circuit riders were so relentless in their ministry that on stormy days there was a proverbial saying: "There is nothing out today but crows and Methodist preachers."  (from Camp Meetings & Circuit Riders-Untamed Faith on America's Early Frontier, Christian History.)

If it worked before, why not again today?  The only question of success is really, "are we going?"
