Dear Karen,
Spain would be ideal for that, since depending on where you go, wheat fields are in different state and shape (due to our various climates especially in the south of the country). Filming infrastructure is excellent and weather conditions the most stable ones in Europe. If you consider coming to Spain, please have a look at our website http://www.frescofilm.com to check our credits, or contact me under peter@frescofilm.com in order to give me more details about the shoot and me being able to send you reference pix and occasionally a budget. Greetings from Spain, Peter Welter Soler, Production Manager, Fresco Film Services S.L. Spain
