If you want to cast a ballot in the June 10 primary, you need to register by May 10.
May 10 is a Saturday, and the Lancaster County Voter Registration office at the County Administration Building, 101 N. Main St., will be open from 9 a.m. to noon that day, said election official Cassie Stump.
However, the office encourages residents to register before then.
You'll need your driver's license with your correct Lancaster County address on it, and your Social Security card.
