Take your family or friends to a picnic or a day on the brooklyn botanical garden, the flowers are so vibrant it’ll cheer you up in no time. They’re open in the spring to summer, I believe. The best time to go is during the cherry blossom season, they have a space for you to sit down and take in the daylight next to the cherry blossoms.. tickets are $22 dollars each person for a whole day. Comment for questions.
