Sister Donna Quinn, a Palos Hills resident, attended the last two and is flying to this one with four other nuns. Rev. Nan Conser, a retired United Church of Christ minister in Golf, never went before but is going with a group of 10 clergy and lay people. Rev. Larry Greenfield, an American Baptist minister who leads Hyde Park Union Church, couldn't make it last time, but said he wouldn't miss this one for anything.
