Summers are about fun, but there’s always room to incorporate a bit of history into the fun! Free Museums on Long Island can be a great way to spend a “not so great” rainy day indoors, or a very hot day indoors to keep cool in the A.C. It’s up to you, and it’s all totally free from Nassau County through Suffolk County.
