I really encourage people to take advantage of their local State Cooperative Extension Agents. Remember Hank Kimball on the old television series Green Acres? Well, they are very knowledgeable and free. Well, not free because we pay for them with tax dollars. So I say take advantage of their expertise. After you get in contact with one, they are usually not so busy and they love to help. My experience at least. They are usually connected with a state university.
