Ignoring the sweltering heat and high humidity, Gregg Murset, his wife and his six children are spending a few hours cleaning up the Oliver family's back yard in Elkridge.
"That's what it's like here in Elkridge. It's very community-oriented and everyone's there for everybody else," said 18-year-old Bo Oliver.
But the Mursets aren't from Elkridge.
They've traveled more than 3,300 miles from Phoenix, Arizona in a 33-foot RV to help dozens of families like the Olivers who need a helping hand.
A few years ago, Bo Oliver was diagnosed with Ewing's Sarcoma, a bone cancer, which the Howard High graduate kicked in January after extensive chemotherapy, radiation and stem cell transplants.
"We were all moving forward and then in March, a spot came back and was found on his upper arm,” said Kathy Oliver, Bo’s mother, “So now we're doing the chemo, the radiation and the bone marrow transplant so you just kind of go, 'I don't get it, but this is the journey that we're on... we're supposed to be traveling... so we're moving forward."
Gregg Murset had always hoped to take his family across the country, but he wanted the summer trip to be a lesson in life for his children.
"See the world as a bigger place and do something about it,” said Murset. “Get off the couch. I think a lot of kids these days are stuck on the couch and they're messing around on their phone or their tablet when they could really be doing something and so that's the driving force."
They tackle the mundane; the overgrown fences or dusty furniture of families struggling with challenges that consume all of their time, attention and resources, and at the end of the day, it's those good deeds by some total strangers that are truly making a difference.
"First and foremost, it definitely restores our faith in humanity,” said Kathy Oliver. “I mean these are people that don't know us that are just coming out and spending their time and their energy and their kids' summer to help us. It's very humbling and very overwhelming."
Murset says they’re kind of like the Partridge family, that musical family that traveled around in a bus back in the 70’s, but instead of playing instruments, they pull weeds.
So far, they've stopped off in 17 cities to perform more than 200 chores.
