This is on June 13th and 14th (which is a month ago)?
Although it was many years ago, I went to an observed trials that was held out in the Superstition Mountain area, East of Phoenix.
Many VERY LARGE boulders and twisty, turney little trails.
I was standing on top of a boulder watching when several people around me started hollering at me and flailing their arms.
At first, I didn't know what their trouble was but I moved towards them.
As I did, suddenly a trails motorcycles front wheel emerged over the edge of the boulder I had been standing on. The motorcycle climbed up on top and stopped. Without putting his feet down, he popped the clutch, raised the front wheel in the air, turned 90° to the right, let the front wheel down and proceeded to almost fall off the far side before proceeding on his very slow, way.
Totally unbelievable riding.
