- Arrive Early: For popular festivals like the Cultural Festival at Mercer County Park, arriving early helps you beat the crowds and snag the best parking spots.
- Stay Hydrated: Even in early June, the sun can get strong. Bring a reusable water bottle, especially for all-day events at parks like Cadwalader or Mercer County Park.
