It is unlawful for any person to enter into or upon any land of another or willfully to go or remain upon the land of another after having been warned by the owner or occupant thereof not to trespass thereon. For the purposes of this section, any clearly legible sign warning against said trespass which is posted prominently on said property so that it may be read from the boundary thereof shall be presumed to be sufficient warning within the meaning of this section and shall revoke any implied invitation to enter upon said land. (Ord. 3343 § 1 (Exh. A), 2019; Ord. 3253 § 2 (Exh. B), 2017; Ord. 29 § 6, 1959)
