"Hi-Lawn is the summertime hangout spot for adults who want to play outside all day. The Union Market rooftop, which is covered in astroturf, has lawn games like cornhole and wooden picnic tables where you can relax (just reserve a table beforehand if you want an umbrella). They also host trivia nights and live music events. Get juice boxes full of your favorite spirits at the bar, but skip the small bar food menu and grab something from one of the stalls downstairs. And if you bring your own blankets, you can enjoy it in true picnic style." - omnia saed, tristiana hinton
