It's just a day away: the darkening streets will fill with witches, goblins, ghosts, imperial storm troopers, Harry Potters and zombies. 

But there's one boy in Saskatoon who will be trick-or-treating by roaring down the streets, and he'll have a sweet new ride to do it. 

Seven-year-old Henry Craig-Van Vliet has cerebral palsy and uses a wheelchair. But this year for Halloween, it's gotten more than just a new paint job. 

An instructor and his industrious students at Saskatchewan Polytechnic decided to turn the youngster's wheelchair into something resembling a chopper, a Henry Davidson, riffing on the well-known motorcycle manufacturer.

"They made it real-like," Annie Bradford, the boy's grandmother said, impressed by the work. "Actual spark plugs, real air filter and of course, the V of the Harley."

Even though Henry is not able to verbally communicate, it was clear he was excited about the specialized chair. His educational assistant, Monika Cwik, said the kindness shown is impressive.

"Unbelievable," Cwik said. "Ten random people who have never met Henry go out of their way to do something so special. It's definitely made his year."
