Join us as we celebrate the US Coast Guard's 235th birthday! There will be no cost for admission to the Great Island Common in New Castle, NH after 5pm (it's the best viewing spot to see the epic firework show). We ask that you bring non-perishable food to donate to the Portsmouth food bank - Gather. Food will be collected at the main gate when you enter the park. The bravery of the surfmen one hundred years ago manning row boats in storms to help mariners in distress is not something we just want to talk about in the museum; we also want to celebrate that tradition in the current day - we call this Helping Others, Then and Now. Your food donation will support a hunger-free community.
