It's been going on since the early 70's in Northumberland County. The 46-year-old tradition in Northumberland County brought people to King Street Park in the borough of Northumberland. Pineknotter Days is held every year during the first week of July. Food, games, live music, and crafts are some of the ingredients of a fun event. And it perfectly describes Pineknotter Days. However, this year... it was the heat which got to people... so turnout was somewhat smaller on Wednesday.
