A pioneer picnic is from 1 to 3 p.m. Aug. 3 at Sacajawea State Park in Pasco.
A short history of the park will be given to visitors, and anyone can bring an instrument and join in a jam. There will be cars from the Old Time Car Club on site.
Admission to the park requires a Discovery Pass, which costs $35 a year or $11.50 for a day pass. The passes are available at discoverpass.wa.gov.
