A PA28 SINGLE PLT CUT OFF ANOTHER SMA DURING THEIR RESPECTIVE ROLLOUTS ON INTERSECTING RWYS AT 3O7.

Narrative

I DIVERTED TO HOLLISTER (3O7) FROM A PLANNED FLT TO MRY. I HAD NEVER BEEN TO HOLLISTER; AND WAS UNFAMILIAR WITH THE ARPT LAYOUT. APPROX 8 MI OUT; I CALLED FOR A TA ON THE CTAF FREQ. ACFT Y IN THE PATTERN ADVISED THAT RWY 31 WAS IN USE; AND THAT WINDS WERE LIGHT. SHORTLY THEREAFTER; ACFT Z RPTED BEING 6 MI N; INBOUND FOR LNDG ON RWY 24. ACFT Z WAS THEN ALSO ADVISED THAT RWY 31 WAS IN USE. I CALLED DOWNWIND AND BASE FOR RWY 31. I HEARD NO FURTHER CALLS FROM ACFT Z UNTIL I WAS TURNING FINAL FOR RWY 31; AT WHICH POINT ACFT Z RPTED FINAL FOR RWY 24. I SPOTTED ACFT Z; PERCEIVED NO CONFLICT; AND CALLED SHORT FINAL FOR RWY 31. I CROSSED RWY 24 ON MY LNDG ROLLOUT; EXITED ONTO THE PARALLEL TXWY; AND CALLED CLR OF RWY 31. AS I WAS XING RWY 24 ON THE TAXI TO PARKING; ACFT Z ALERTED ME TO THE FACT THAT HE WAS STILL ON RWY 24. ACFT Z; AT THAT POINT; APPEARED TO BE AT NORMAL TAXI SPD; APPROX 75-100 FT AWAY AT MY 8 O'CLOCK POS. NEITHER ACFT HAD TO TAKE ANY EVASIVE ACTION; AND BOTH CONTINUED TAXIING TO PARK. THIS WAS A POTENTIALLY HAZARDOUS SIT; HOWEVER. THIS SIT OCCURRED BECAUSE I ALLOWED MYSELF TO BECOME DISTR INSIDE THE COCKPIT WHILE TAXIING ON AN UNFAMILIAR FIELD. A CONTRIBUTING FACTOR WAS ACFT Z'S USE OF A XING RWY AFTER BEING ADVISED THAT OTHER ACFT WERE USING RWY 31. I HAVE SINCE REVIEWED THE FAA'S MATERIALS ON PREVENTING RWY INCURSIONS; FOLLOWING THE RECOMMENDATIONS CONTAINED THEREIN WILL PREVENT A RECURRENCE.
