Friends and family of a Navy fighter pilot performed "acts of random kindness" in Garland in his memory.
Lt. Matt Shubzda died in a Navy training exercise 10 years ago.
"Today is about Matt and honoring his legacy of service," said Cortney Schwalbe, his best friend and organizer of Shooby Still Serves.
Schwalbe and her husband, who is deployed in Afghanistan, made it their mission to keep their best friend's legacy alive.
"We wanted to turn a tragic day into a positive one and help serve people," she said.
The acts ranged from handing out sandwiches to people without jobs to sending donations to a women's shelter and the Garland Veterans of Foreign Wars.
Patti Shubzda said she always carries her son with her and is grateful to see his spirit in action.
"So many people after this length of time to still care and still remember," she said. "It just makes my heart want to burst with happiness."
"Ten years ago, I thought life was going to get sucked out of me and I'd never be OK, and today I'm so grateful for the life he lived," she said.
"It is going to so much to so many people that you don't realize how grateful these people will be," said David L. Jones, of the Garland Veterans of Foreign Wars Post.
In all, the group raised $3,000 in cash and donation for local groups in the city and people all over the world will be doing acts of random kindness, or ARKS.
But the group doesn't want them to end today.
"I think today is not just about serving, but having a legacy of service and making that part of your lifestyle," Schwalbe said.
Matt Shubzda graduated from Naaman Forest High School in 1994 and attended the Naval Academy.
