AG exemption?
Simply zoned AG if anything. Can’t really call it an exemption since most of the State is this way. No building dept or codes, no restrictions.
The previous county we lived in had no physical addresses or 911 service. If you called, someone from the nearest city PD might answer. Mailing addresses were for and made up by USPS for mail delivery. RR 2 box 305 = Rural Route 2, mailbox #305. Ebay sellers would freak out seeing Box 305 and assume it was a PO box.
Wild, Wild West.
