A bunch of guys and a bunch of lawn mowers.
That's the basic idea behind the volunteer Detroit Mower Gang - which cuts the grass at city parks in Detroit every other Wednesday night.
This past week, the Gang mowed about 25 acres in Stoeppel Park Number Two on the city's west side.
Barbara Davis lives across from the park - where for many kids, the grass was chest-high.
"It's terrible," said Davis. "They usually got to cut a path and tramp right to the swing set because the grass is so tall. But I really appreciate these guys coming out here and helping us out."
The Mower Gang started in 2010 by Tom Nardone.
"We try to pick parks that have playground equipment so little kids can play," said Nardone. We try to pick parks where people live nearby, where people are trying to use the park even though it's not being mowed, and we try to look for ones that the city doesn't mow."
Nardone and his gang mow every other Wednesday. The group started in 2010.
