Narrative:
Event was non-threatening to anyone, except perhaps the aircraft. Landed on runway 34L at seattle and turned off on taxiway H and cleared to cross runway 34R to ramp. Parking is on a concrete/asphalt area near post office. Crossed runway 34R and saw the ground guidance coordinator with the wands and turned toward him. Unfortunately this took me across a stub of grass that is between txwys a and B. It is unlighted and blends in at night. The yellow line leads around this but I believed I was on the ramp, as if already on taxiway a. No harm done, but I think the issue is time of day (night), fatigue and a brief lapse of attention. Ironically, been flying this same route for a yr and have thought many times 'one of these days I'll be tired and go across that grass.' the solution is more attention when tired and the area should be lighted.

Title: CAPT OF A DC9 INADVERTENTLY TAXIED OFF THE TXWY INTO A GRASSY AREA BTWN THE TXWY AND RAMP DURING NIGHT TAXI TO PARKING.
Narrative: EVENT WAS NON-THREATENING TO ANYONE, EXCEPT PERHAPS THE ACFT. LANDED ON RWY 34L AT SEATTLE AND TURNED OFF ON TXWY H AND CLRED TO CROSS RWY 34R TO RAMP. PARKING IS ON A CONCRETE/ASPHALT AREA NEAR POST OFFICE. CROSSED RWY 34R AND SAW THE GND GUIDANCE COORDINATOR WITH THE WANDS AND TURNED TOWARD HIM. UNFORTUNATELY THIS TOOK ME ACROSS A STUB OF GRASS THAT IS BTWN TXWYS A AND B. IT IS UNLIGHTED AND BLENDS IN AT NIGHT. THE YELLOW LINE LEADS AROUND THIS BUT I BELIEVED I WAS ON THE RAMP, AS IF ALREADY ON TXWY A. NO HARM DONE, BUT I THINK THE ISSUE IS TIME OF DAY (NIGHT), FATIGUE AND A BRIEF LAPSE OF ATTN. IRONICALLY, BEEN FLYING THIS SAME RTE FOR A YR AND HAVE THOUGHT MANY TIMES 'ONE OF THESE DAYS I'LL BE TIRED AND GO ACROSS THAT GRASS.' THE SOLUTION IS MORE ATTN WHEN TIRED AND THE AREA SHOULD BE LIGHTED.
