Narrative:

Cleared to taxi to 19L via delta. Taxied to the end of runway, completed run-up, and called tower for takeoff. Tower responded with 'taxi into position and hold.' I did so. Tower called and asked me 'location, please?' I looked at runway #'south and idented 19R and asked if I should clear. Tower said 'no,' and cleared takeoff. Considerations: 1) I was unfamiliar with airport. 2) immediately preceding flight I had problems with FBO who had charged me for fuel, but had not done so. 3) as I taxied, I recall identing 19L as being on my left (error). Corrective action: never taxi west/O an airport diagram in my lap. Verify and double check runway and taxiway identify. Concern: this one really got my attention. I could easily have precipitated an accident.
