The Farmer and The Chef
Instead of having food festivals and farmers markets separate from one another, how about pair farmers and food vendors side-by-side at a combined farmers and food market, where chefs cook up tasty meals built from the farmer's bounty.
This concept could go one of two ways, or both.
1. Have food vendors pair up with farmers at the more frequent farmer's markets
and, or 2. Include farmers at food festivals
These two different events often draw different types of people, consequently the different venues would reach a broader audience. The message is the same at both however - the celebration of food goes side-by-side with the celebration of its production
