Inexpensive & Free Things to do in Brooklyn
"A great way to see one of the best museums in the city at the Brooklyn Museum is by taking advantage of their free admission days on the first Saturday of every month from 5 pm to 11 pm (except for the months of January and September). But if that doesn’t work out with your timeline, don’t fret as you can still enjoy the museum as they have a pay-as-you-wish admission which makes art accessible to everyone, even if you’re on a tight budget. This museum is one of the best free and cheap things to do in Brooklyn for many reasons."
