On August 13, 1921 a road between Winlock and Cowlitz Corner was completed. There was a big celebration commemorating the event, and since Winlock was becoming quite a famous poultry center, they decided to call the celebration "Winlock Poultry and Egg Day." There were about 1,000 people present at the celebration. Otis Roundtree was the General Chairman for the event. After the celebration, it was decided to make this an annual event, which was done.
