Narrative:

Taxiing out for takeoff on taxiway foxtrot for runway 28L and P intersection takeoff. Tower cleared us for takeoff on runway 28L. I turned left rather then right onto taxiway P which leads to runway 28C. Fortunately pit tower saw our mistake immediately and told us we had turned the wrong way. We stopped short of runway 28C. Tower then cleared us onto runway 28C to do a turn back to runway 28L. Departed on runway 28L as instructed. Problem happened for 3 possible reasons. We were fatigued after being on duty for 8 hours with little time to take a break due to avoiding thunderstorms all day. This was leg #6 for the day. First officer and myself had not operated at pit in quite a while. Nighttime -- dark. Callback conversation with reporter revealed the following information: the captain said that he was very fatigued after flying the dehaviland dash 8-100 all day. He said that the crew was not familiar with the airport as they no longer go there as much as they used to in the past. The flight crew was used to working together he said and he attributed the error to the things mentioned in his narrative.
