Arrived about 10am with Jaclyn and Marga. Cool, mostly sunny, high thin clouds. Nice wind from the west. The rice field is knee high in weeds and they will get sprayed with herbicide today and fertilizer to follow. Maybe start flooding the field next week. Talked with Dennis Pallucca. They need an expert on great garter snake.
