Unsolved: Picnic Panic

Unsolved: Picnic Panic is a quest in the Fallout 76 update Wild Appalachia.

Detailed walkthrough
The quest begins upon reading the note on Calvin van Lowe's bulletin board in his room at Van Lowe Taxidermy or pinned to the bottom of the bulletin board in Grafton Station. Head to the picnic site south of Wavy Willard's Water Park and investigate the scene, look for an empty box of rat poison, two bicycles belonging to "Chelsea Wesley of Clarksburg" and Mary Tinley and a holotape. After examining everything, head to the Wesley house in Clarksburg, dealing with any robots or feral ghouls encountered, as the house is on the east side of the ruins, immediately west of the Clarksburg Shooting Club. Find Chelsea's diary page along with a horseshoe magnet and dice before being directed to the Tinley family trailer on the west side of town. Deal with Harvey Tinley, who has become a feral ghoul and is still present there, and find Mary's diary page in a backpack inside, which completes the quest and solves another of the unsolved mysteries that Calvin believed would lead to the Sheepsquatch.
