I spent yesterday with a few other families that also have kids on bikes at a kid-friendly dirt park south of us. I was getting a little overly comfortable at speed there, and ran straight into a hole that I hadn't seen ahead of time. I hit the hole probably at 50 - 60 mph, it was about 3 feet in diameter, and about 1 - 1.5 feet deep. Unfortunately I didn't clear it, so the front wheel slammed into the far wall with some pretty great force. It knocked the bike up in the air, and knocked me off the side of it. I was fortunately OK, but the bike did take some damage. Rear brake pedal was taco'd all the way up and around, brake lever was bent, and controls were rotated around. The handlebars were also off-center by at least 10 - 15 degrees, as the forks had twisted quite a bit from the impact. Friends helped me bend the brake pedal back to usable, and the brake lever back in shape as well. We then loosened the triple-tree for the forks, which allowed me to straighten the wheel back to center, and re-tighten. I hope that the forks themselves didn't bend, but they looked reasonably OK afterwards. Some cosmetic damage to the right side of the bike, but I guess that's what a dirtbike is supposed to look like at some point; it was a little too clean before this get-off. Fortunately I didn't do much damage to me, though I am pretty sore on the left side of my body. Nothing that alcohol and/or painkillers won't be able to deal with, I'm hoping.
