Youth Day will be observed on Sunday, at St. Timothy’s Episcopal Church, 630 Mississippi Ave., Signal Mountain. Youth will be conducting the 10:30 a.m. service, serving as greeters, ushers, acolytes, lecturers, music worship and oblation bearers. There will also be a special Pentecost skit and homily. Following the service there will be a picnic lunch on sale in the Parish Hall as an EYC mission trip fundraiser. Bring your blankets and chairs to enjoy Sunday on the Grounds with lunch and live jazz music.
