What city grows from 65%-80% of the world's horseradish, claims to be the Horseradish capital of the world, and has an international festival for the beloved herb?

I love it, would it be Collinsville Illinois?

Let the ink dry, man. Of course, you are right. Other cities make the claim, but the lowest figure I saw for Collinsville's share of the market was 65%, which makes any other claim laughable. My dad wanted me to work on a horseradish farm one summer. I knew a guy that did, and told Dad I would run away from home first. Working the fields on a horseradish farm involves bending down at dawn, straightening back up at 9 for 10 or 15 minutes. back down until lunch at 11:30, bending back down at noon, and quitting at 3.
