Until Sunday, Garfield Park-goers have the opportunity to use a temporary medium to say something powerful.
Ashland High School seniors Ashlynn Tapp and Sadie Kasiah built a chalkboard inviting passers-by to complete the phrase "Before I die ..." as part of their senior project.
Each day they record the messages and then clear the board for the next day's comments.
"It was definitely worth making, because it's really inspiring seeing others' dreams," Tapp said.
She said many of the things written have been personal goals, or places to visit.
"Most, well, a lot, have to do with traveling," she said.
But she said many are lighthearted, such as "I want to see the Dodgers win the World Series."
Some are particularly moving, Tapp said.
"I've seen some really touching ones, like, 'I want to be comfortable with myself' or 'I want to see my kids happily married.' "
Even though the slate gets wiped clean doesn't mean the goals get erased.
"We decided to keep them in a notebook, and maybe present them during our presentation," she said.
Tapp said they wanted to make something to remind people of their goals.
"Our main goal for the project was to get people to think about their goals and what they want to do."
