"I sat there and watched that guy do what he does. It's unbelievable," says Earl Gross, a Harley Davidson motorcycle owner.
You might have seen Mark Brodie's work on trailers at Nascar, in magazines, or on motorbikes.
"Oh, it just jumps out at you. It really does," says Elton Christopherson of Brodie's design.
"You know, a guy came into my dad's car lot years ago in Colorado. And I was already messing around with an airbrush," says Brodie. "But he came in and opened the trunk of his car and went right to work right there and I thought it was the coolest thing I'd ever seen. So I got a set of brushes the next day and I have never ever looked back," he says.
That thing, pinstriping, is Brodie's specialty.
It involves applying thin lines of paint to form a design.
"Just to give it that little edge. That little extra. As opposed to what it looked like stock," explains Brodie.
Brodie's profession allows him to combine many passions.
"I've always been into art. I've always been into cars and motorcycles so it all went hand in hand," says Brodie.
He's been doing pinstriping for so long, he's lost track of how many designs he's done. And each one is an original.
And because of that originality, bikers say the designs allow owners to give their bikes a personalized look.
"It's a great thing to do to your motorcycle, for sure. Because your motorcycle is very personal to you. And so it just kind of brings out the best in it," says Gross.
While his artwork adorns countless bikes, Brodie's not out of design ideas just yet.
"I'm going to stick with it for awhile until I can't do it anymore," says Brodie.
While you can find Brodie's designs in many places, when he's not working, you're likely to find him in just one spot-hitting the road in his RV, with his dog, Boomer.
Brodie will be back at Black Magic Harley Davidson in Williston tomorrow. He will be at Magic City Harley Davidson in Minot next week.
