Priscilla Vega hoists Alexandria MacKneer, 7, while daughter Pallis Vega, 3, hangs on at Cranberry Community Township Waterpark on Monday, June 28 2021. The three were taking part in the Rochester Salvation Army day camp, which traveled to the pool to cool off. As temperatures rose into the 90s, staffing shortages forced the temporary closure of some pools in Allegheny County, among them Settlers Cabin, South Park, Boyce Park and North Park (Steve Mellon/Post-Gazette)
