Narrative:
Third and final leg of 3 day trip (20 hours in 3 days). Crew tired. Approach continued. Used wrong call sign once. Clear and calm night. Cleared visual runway 34L behind another aircraft. Saw this aircraft land and roll out and clear runway. After landing we may have switched frequencys as we cleared runway but were then on approach control. Were told to switch tower frequency to cross runway 34R and did so. We have no recollection of being cleared to land but tower never said a thing. 1 man in tower covering ground, clearance delivery, and tower frequencys.
