The BMX riders who have built ramps and jumps in the southeast corner of High Park are being challenged by one man who says they are dangerous and illegal.

Adrian Rhodes also alleges that the man-made hills have disrupted the natural environment of the area. Rhodes has lodged a complaint at City Hall and has requested that Toronto's parks and recreation department look into the issue.

Kevin Bowser, manager of parks and recreation Etobicoke York District, told InsideToronto that assessment of the environmental damage in the area is being conducted. "It's my understanding they've been there 20 to 30 years. This is not a new issue," he said.

But it's still an important one to Rhodes. "People, walkers and joggers go through these trails," he said. "An accident is a huge liability."

So enjoy your ramps while you can, punks.
