Trespass when a person “knowingly enters or remains unlawfully in a building or upon real property which is fenced or otherwise enclosed in a manner manifestly designed to exclude intruders” carried a heightened penalty, and trespass against a “building used to shelter, house, milk, raise, feed, breed, study or exhibit animals” carries an even more heightened one.  Del.
