PITTSBURG, Kan. — With less than three weeks until the start of the school year, parents are anxiously waiting with bated breath for the USD 250 Board of Education and local health officials to make a decision about masking in classrooms for the upcoming school year. “As a parent, I am extremely frustrated that the school board and the health officials are continuing to postpone this decision until less than one week before school is scheduled to start,” said Heidi Casper, a local and mother of six. Of Casper's six children, four are school-aged, two will be attending elementary school — where the largest group of unvaccinated children will be — and one of the elementary-age children is immunocompromised.
