Narrative:

I also didn't expect to be directed to runway 19R for takeoff since I was coming from an FBO on the east side of the ramp. Since jet traffic was using 19R, I expected to be put on 19L. After my runup, I was instructed to taxi north on C and hold short of runway 19R before calling the tower. I don't believe that I read this back. Since my taxi clearance didn't include (or I didn't hear) a 'hold short of runway 19L,' I believed I could cross runway 19L on my way to runway 19R. When reaching the north end of the taxiway, I turned, crossed the end of runway 19L, and stopped at a hold line. When I called the tower, I was informed that I 'had crossed an active runway' and that I was still on runway 19L. The airport was much larger than what I'm used to and in the dark I mistook runway 19L's west side hold line with runway 19R's east side hold line. I taxied forward, was cleared for takeoff after some traffic cleared, and flew back to cable. The flight north was routine and my plting performance seemed normal.

Title: UNAUTHORIZED RWY ENTRY XING OP.

Narrative: I ALSO DIDN'T EXPECT TO BE DIRECTED TO RWY 19R FOR TKOF SINCE I WAS COMING FROM AN FBO ON THE E SIDE OF THE RAMP. SINCE JET TFC WAS USING 19R, I EXPECTED TO BE PUT ON 19L. AFTER MY RUNUP, I WAS INSTRUCTED TO TAXI N ON C AND HOLD SHORT OF RWY 19R BEFORE CALLING THE TWR. I DON'T BELIEVE THAT I READ THIS BACK. SINCE MY TAXI CLRNC DIDN'T INCLUDE (OR I DIDN'T HEAR) A 'HOLD SHORT OF RWY 19L,' I BELIEVED I COULD CROSS RWY 19L ON MY WAY TO RWY 19R. WHEN REACHING THE N END OF THE TAXIWAY, I TURNED, CROSSED THE END OF RWY 19L, AND STOPPED AT A HOLD LINE. WHEN I CALLED THE TWR, I WAS INFORMED THAT I 'HAD CROSSED AN ACTIVE RWY' AND THAT I WAS STILL ON RWY 19L. THE ARPT WAS MUCH LARGER THAN WHAT I'M USED TO AND IN THE DARK I MISTOOK RWY 19L'S W SIDE HOLD LINE WITH RWY 19R'S E SIDE HOLD LINE. I TAXIED FORWARD, WAS CLRED FOR TKOF AFTER SOME TFC CLRED, AND FLEW BACK TO CABLE. THE FLT N WAS ROUTINE AND MY PLTING PERFORMANCE SEEMED NORMAL.
