Narrative:

While on the GA ramp, sgj was given instructions to 'taxi to runway 6, don't block runway 2, it's being used as a taxiway.' having been to this airport once in the past I recalled a strange intersection between the ramp and the approach ends of runways 2 and 6. I had mins earlier consulted the airport diagram in the airport facilities directory before landing and passing through this intersection on my way to the ramp. As I exited the ramp I saw the signage for runway 2/20 seeing there was not room before runway 2 to do a run-up, and not wanting to 'block runway 2,' I continued intending to stop at the runway 6 hold short line. The next surface markings I saw was the '6' on the runway surface as the nose of the aircraft was approaching it. Realizing I had strayed onto the runway I quickly accelerated across it and notified ground control of my mistake. No evasive action was received by any other aircraft. As I was departing I didn't have a chance to take another look at the markings and signage. I don't recall seeing a runway 6/24 sign as I approached it. I also don't recall seeing a hold short line for runway 6/24. After further review of the airport diagram I think runways 2 and 6 must have a common hold short line at the exit from the ramp. The runway 6/24 sign may not be in a standard location because of the layout of this intersection. I also think what the controller meant by 'taxi to runway 6 but donT' block runway 2 it's being used as a taxiway' must have been, hold short and doing run-up somewhere on the ramp, but not at the hold short line. Stopping at the hold short line, or anywhere on the short taxiway would have blocked aircraft entering the ramp from runway 2. Finally knowing of the confusing geometry of this intersection I should have asked for clarification from the controller.

Title: THE PLT WAS TOLD TO HOLD SHORT OF THE ACTIVE RWYS. HE MISSED THE RWY SIGNS OF 2 RWY ENDS THAT INTERSECTED. HE CROSSED 1 RWY AND INCURRED THE SECOND RWY WHEN HE REALIZED HIS ERROR.

Narrative: WHILE ON THE GA RAMP, SGJ WAS GIVEN INSTRUCTIONS TO 'TAXI TO RWY 6, DON'T BLOCK RWY 2, IT'S BEING USED AS A TXWY.' HAVING BEEN TO THIS ARPT ONCE IN THE PAST I RECALLED A STRANGE INTXN BTWN THE RAMP AND THE APCH ENDS OF RWYS 2 AND 6. I HAD MINS EARLIER CONSULTED THE ARPT DIAGRAM IN THE ARPT FACILITIES DIRECTORY BEFORE LNDG AND PASSING THROUGH THIS INTXN ON MY WAY TO THE RAMP. AS I EXITED THE RAMP I SAW THE SIGNAGE FOR RWY 2/20 SEEING THERE WAS NOT ROOM BEFORE RWY 2 TO DO A RUN-UP, AND NOT WANTING TO 'BLOCK RWY 2,' I CONTINUED INTENDING TO STOP AT THE RWY 6 HOLD SHORT LINE. THE NEXT SURFACE MARKINGS I SAW WAS THE '6' ON THE RWY SURFACE AS THE NOSE OF THE ACFT WAS APCHING IT. REALIZING I HAD STRAYED ONTO THE RWY I QUICKLY ACCELERATED ACROSS IT AND NOTIFIED GND CTL OF MY MISTAKE. NO EVASIVE ACTION WAS RECEIVED BY ANY OTHER ACFT. AS I WAS DEPARTING I DIDN'T HAVE A CHANCE TO TAKE ANOTHER LOOK AT THE MARKINGS AND SIGNAGE. I DON'T RECALL SEEING A RWY 6/24 SIGN AS I APCHED IT. I ALSO DON'T RECALL SEEING A HOLD SHORT LINE FOR RWY 6/24. AFTER FURTHER REVIEW OF THE ARPT DIAGRAM I THINK RWYS 2 AND 6 MUST HAVE A COMMON HOLD SHORT LINE AT THE EXIT FROM THE RAMP. THE RWY 6/24 SIGN MAY NOT BE IN A STANDARD LOCATION BECAUSE OF THE LAYOUT OF THIS INTXN. I ALSO THINK WHAT THE CTLR MEANT BY 'TAXI TO RWY 6 BUT DONT' BLOCK RWY 2 IT'S BEING USED AS A TXWY' MUST HAVE BEEN, HOLD SHORT AND DOING RUN-UP SOMEWHERE ON THE RAMP, BUT NOT AT THE HOLD SHORT LINE. STOPPING AT THE HOLD SHORT LINE, OR ANYWHERE ON THE SHORT TXWY WOULD HAVE BLOCKED ACFT ENTERING THE RAMP FROM RWY 2. FINALLY KNOWING OF THE CONFUSING GEOMETRY OF THIS INTXN I SHOULD HAVE ASKED FOR CLARIFICATION FROM THE CTLR.
