could think of, depending on what we we:re doing.
Sometimes we ran with Gordo--if one guy was sleeping,
the other guy would run with his red lights on dim.
And many nights, we ran with no lights at all.
We

lights and we would go through whole night sides without
ever turning the lights on and never even looking at
the instrument panel when we were in dri::ting f light.
