Narrative:

Ground control directed us to taxi from the GA ramp to runway 19R. The ramp leads to taxiway C. I had the nos airport diagram open on my lap. After entering taxiway C and looking for the right place to turn onto taxiway D, I became disoriented or distracted or both. I still don't know how or why it happened, but I continued on taxiway C and entered runway 19R while looking for taxiway D. Only as the aircraft passed over the broad white side stripe of the runway and I saw the black surface from tire marks did I realize I had blundered onto a runway to which I had been cleared. I glanced left and right and quickly continued the crossing to get out of danger. (There was no traffic landing or taking off). I was confused and shaken, and called ground control to say I was lost. The ground controller twice responded, 'no problem,' and instructed me to do a 180 degree turn and depart from the side of the intersection I was on. My wife says I've been especially distracted by business problems that last couple of months. Sometimes concentration creates tunnel-vision. What a lesson!
