Farm Aid is sponsoring a photo contest, whose winner will receive an expenses-paid trip and two front-row tickets to the Oct. 4 concert in St. Louis.

Currently slated to appear are Willie Nelson, Neil Young, John Mellencamp, Dave Matthews, Jason Mraz, Wilco, Phosphorescent and Jamey Johnson.

The event will once again feature HOMEGROWN concessions, with foods from regional family farms and local organic growers. The HOMEGROWN Village will host hands-on activities that give concertgoers a chance to meet family farmers and get their hands dirty.

To enter the contest, shoot a photo of anything related to family farmers and the food they produce. Here are some ideas to get you started: farms, farmers, farm families, tractors, barns, a perfect crop of organic veggies or fruits from your local farmer’s market, your favorite farm animal—any image that shows the vibrancy and beauty of the American family farm.

Photos should be uploaded to the Farm Aid Farm Fresh Pics website by 11:59 p.m. (ET) Sept. 6. You may also vote for your favorite photos until 11:59 p.m. (ET) Sept. 20.
