I’ve even volunteered managing farms in Haiti.

I grew up on a 500-acre small grain dryland farm in France. I always intended to farm, and my interest was drawn to the wide-open spaces, big equipment and scale of farming in the U.S. My interest was confirmed when I had the opportunity to work on an Iowa farm in the fall of 1994 at 17 years old.
