High school seniors marched to the post office Friday to send out thank you notes to the people who helped them get through the arduous process of applying to college. 

Nearly 100 students from Brooklyn Collaborative High Schools participated in the act of gratitude for their parents, teachers and friends. 

"I feel like it helps us, you know, recognize people who were there for us and it just the support we had throughout this whole entire process and that the school gives us the whole entire time," said Ashley Barreto, a senior at Brooklyn Collaborative High School.

Over 2,000 students across the country participated in this march, with students in 25 schools in ten cities. This has been a tradition at the school for the last 11 years, and any of the students say they have been looking forward to this day for years. 

"It was very stressful but I honestly, I got it done before my due date so I think it was just stressful making sure everything was right," added senior Joscelyn Ramos.

Most of the college applications could be filled online, but some students are also sending supplemental documents to make them stand out as well. 

"I've been here since middle school, so I saw the marches in middle school and it feels really good to be here now actually to be doing the marching thing wearing a sweatshirt being seniors it feels good,” said senior Isaac Fliegelman.
