Voting is through Facebook "likes." Participants may vote for as many photos as they like, but only one vote per photo. Share photos on your timeline to help get more Facebook likes for your favorites. The entry period for photos ended November 30, 2018. Voting continues through December 31, 2018 so later entries have time to earn votes too.
If you are not logged into your Facebook account the Share and Like buttons will appear gray and won't be active.
Voting is simple. Unlike other contests that use public vote to collect email addresses, Fields-of-Corn voting supports the entrants. No personal information of the voter is being collected.
