Concertgoers may put out blankets and chairs starting at 8 AM the morning of the Summer Twilight Concert. Tarps are not permitted as they can cause significant damage to the grass and prevent fair access to others. Blankets and towels cannot exceed 10 feet x 10 feet in size. There is no policing of the park so personal items are left at your own risk. If you bring a chair, low back beach chairs are encouraged as they do not block the view of attendees behind you.
