About a dozen red swings installed around Halifax by urban activists are proving a hit with all ages, but don’t count city lawyers among the fans.

The swings were installed earlier this month as part of a festival called 100 in 1 Day. The swings are made of wood and rope, and are fixed to tree branches or other overhanging objects.

"Very relaxing and it's nice to have little things around the city like that," says Gordon Simms, who hopped on a swing Friday across from Dalhousie’s Weldon Law Building.

"Little surprises, I guess, that anyone can use."

Another swing is tied to a tree across from the Hydrostone Market in Halifax’s north end. Gwen Morton is a fan.

"It's awesome," her father, Ashley Morton, says. "It's neat to have just little bits of fun scattered through the city."

But the swings may not last long. Lawyers with the municipality are worried someone will get hurt and sue the city; crews have been told to take the swings down if they spot them on city land.

Halifax’s Waterfront Development Corporation, however, is taking a far more relaxed view after it discovered the swing installed on its boardwalk.

"What we found was a lineup of people waiting to use it, including an elderly couple having a good swing together holding hands," says planning vice-president Andy Fillmore.

"And we knew in that moment that we were going to keep it here. Based on that we're going to try to get a few more on the waterfront."
