Our local farmers put their soy bean and corn in about Mother's Day. As of now we haven't had a freeze in about 2 weeks but most farmers still wait til Mother's Day. Since we've been here, about 34 years now, we have had frost as late as Mat 15 but not for a few years. Our winters are getting shorter or at least have come earlier each year. An old local guy told me the other day..."we don't get winter any more just a cold snap around Christmas then an early spring".
