I have, on the mountain bike. We climbed this long, steep thing called "Bulldog" and we saw Jeeps and other military stuff lying around.
I have also climbed Latigo when the wind was so strong we could not hear each other, even screaming. In those days we used to go to the Rock Store and when we got there two motorcyclists were talking about what a difficult ride they had. We didn't tell them we had done the same route as they did.
