Chelsea-based Youth Dance Theatre (YDT) and guest performers will present an evening of dance Friday, August 10 at 7 p.m. at the Washington Street Education Center Auditorium to benefit Austin Nichols. Austin is a 23 year-old Grass Lake native who was diagnosed with an inoperable brain tumor in March. YDT asks attendees to give a donation; money raised will help pay for Nichols’ medical expenses.
