I have no spot metering available on my AC-5, so I walked to the far end of the tunnel and took the measurement of the bright sunshine there with the camera (1/500). Then I went back to where I took the photo from and set the camera to manual so as to override the 1/30 setting it wanted in A mode. I figured this was way too long and would blow out the light at the far end of the tunnel completely. I set the shutter to 1/500 (the aperture was f8) and hoped the foreground of the photo wouldn't turn out to be too dark. I'm very pleased with the result.
