Pit stop.  Dan Crawfis, Ottawa, of 5 Star Ag fillers 'er up at a filling station in Ada. He's spraying wheat fields this time of year and getting the weeds out of corn fields prior to planting. The $250,000 John Deere sprayer uses diesel fuel, costing close to $400 for a fill up. 5 Star Ag, of Pandora, sprays about 25,000 acres. (Monty Siekerman photo)
