Best advice I would give anyoneSonoma County Mike said:Find out where people would have walked, try and picture the area in your mind on how it may have looked 50 to 100 years ago. Hunt around the old buildings. Hunt the path between the main house and the outhouse. If outhouse is not visible, look for depression in the field behind house. Hunt under old clotheslines. Hunt around any large old trees, family picnics usually happenend around trees with the most shade. See if there are any old foundations. Dig everything!
