House committee substitute to the 1st edition modifies the proposed changes to GS 136-129 to exempt specified outdoor advertising promoting a bona fide farm from the prohibition on outdoor advertising within 660 feet of the right-of-way of the interstate or primary highway system. Expands the proposed exemption to include outdoor advertising promoting a bona fide farm exempt from either county or city zoning regulations, rather than only county zoning regulations. Additionally, now requires the sign to be located on any bona fide farm property owned or leased by the owner or lessee of the bona fide farm (previously limited the location to the bona fide farm property).
