Narrative:

Cleared to taxi to runway 18 at which time I began my taxi. I taxied across runway 7/25 and had traveled another 1000 ft when ground advised me that I was cleared to taxi to runway 18 and did I want another runway. I immediately realized I was taxiing to runway 36, apologized, turned around with a clearance to cross runway 7/15 and taxi to runway 18. In taxiing to runway 36 I had crossed runway 7/25 without a clearance. There was no traffic landing or departing any runway at lebanon, nh. At the time and after I had been cleared to cross runway 7/25 ground control began working another plane. This was my second time at lebanon and I was disoriented with runway placement on taxi. I accept full responsibility for the error in taxiing to the wrong runway. In the future I will keep my commercial diagrams open even in VFR WX at airport I am unfamiliar with. There are no markings off the ramp at lebanon to indicate where runway 18 begins. As it turns out, runway 18 is almost right next to the GA ramp.

Title: A CESSNA 182 PLT CROSSED A RWY WITHOUT CLRNC AT LEB.

Narrative: CLRED TO TAXI TO RWY 18 AT WHICH TIME I BEGAN MY TAXI. I TAXIED ACROSS RWY 7/25 AND HAD TRAVELED ANOTHER 1000 FT WHEN GND ADVISED ME THAT I WAS CLRED TO TAXI TO RWY 18 AND DID I WANT ANOTHER RWY. I IMMEDIATELY REALIZED I WAS TAXIING TO RWY 36, APOLOGIZED, TURNED AROUND WITH A CLRNC TO CROSS RWY 7/15 AND TAXI TO RWY 18. IN TAXIING TO RWY 36 I HAD CROSSED RWY 7/25 WITHOUT A CLRNC. THERE WAS NO TFC LNDG OR DEPARTING ANY RWY AT LEBANON, NH. AT THE TIME AND AFTER I HAD BEEN CLRED TO CROSS RWY 7/25 GND CTL BEGAN WORKING ANOTHER PLANE. THIS WAS MY SECOND TIME AT LEBANON AND I WAS DISORIENTED WITH RWY PLACEMENT ON TAXI. I ACCEPT FULL RESPONSIBILITY FOR THE ERROR IN TAXIING TO THE WRONG RWY. IN THE FUTURE I WILL KEEP MY COMMERCIAL DIAGRAMS OPEN EVEN IN VFR WX AT ARPT I AM UNFAMILIAR WITH. THERE ARE NO MARKINGS OFF THE RAMP AT LEBANON TO INDICATE WHERE RWY 18 BEGINS. AS IT TURNS OUT, RWY 18 IS ALMOST RIGHT NEXT TO THE GA RAMP.
