Hillclimbs have been a part of motorcycling since the decline of board track racing in the 1910s. They're still big, especially with riders of vintage motocross bikes, who flock to the Hillbilly Hillclimb at Glen Helen. Cross-dressing optional.

This week on RideApart, Jamie Robinson procures a $150 Yamaha TY250, tosses it into the back of a Honda Ridgeline and joins the throng of vintage-bike lovers at the Hillbilly Hillclimb, the brainchild of Meatball, a classic moto enthusiast.

What's with all the cross-dressing, you ask? Ain't nothing but a thang.
