I was in college on johnson street, went outside for some fresh air in hot apartment and laid in grass. saw two ufos. one was black disc about a mile away chaning directions and moving behind clouds. the other was white with auras and seemed to give off rays as if electrified. both were at the same time. happened after another event, the time of a strange loud sound in town for about a month. sounded like metal being dragged on concrete.
