A PPL friend and I flew there with another friend and an instructor from the San Diego FBO we rented from - the instructor was a condition of the rental! I seem to recall him pointing out skid marks about half way along the runway as the uphill portion of 22 crests the rise!
DC-3 and a Bushmaster 2000 (1960s update of the Ford Trimotor) followed us in a few minutes later.
