California tractor exchange program produces cleaner air

Each winter, an international agricultural equipment exposition – the World Ag Expo – comes to California’s bread basket – the San Joaquin Valley and in Tulare in particular. WAE draws people from all corners of the globe. Like some of the equipment on display, this three-day extravaganza is huge. I have been there but once. WAE … Read more
