The document summarizes the story behind an historical marker located on Highway 83 between Mission and Sullivan City in Texas. It describes how the marker commemorates Jim Sullivan, who sold his land to fund an unsuccessful search for oil. However, the man who purchased Sullivan's land, John Lawrence, struck oil there in 1934 in one of the highest producing wells in Texas. Though Sullivan did not find riches through oil, the nearby town of Sullivan City was named in his honor as a lesson about persevering in pursuit of one's dreams.
