I have been to Agro Expo Irapuato in Irapuato Mexico and to the expo in Culiacan Mexico. This was back 10 or 12 years ago. Both are big shows with lots of things to see. Grain and vegetable production, seed companies, equipment and even green houses on site with production going on. There are also outdoor plots of corn, sorghum and dry beans. I have also been to a big dealer show in Pato de Minas Brazil. Really done up big time with demonstration plots, fertilizer and herbicide companies and equipment. They also have special discounts for purchases during the show and sell about 60% of the years volume in 2 1/2 days. All of them were worth seeing and very interesting.
