Narrative:

While taxiing to runway 22/intersection M, I was cleared to cross runway 12L. I inadvertently missed intersection M, and continued to taxi toward the end of runway 22, crossing runway 12R without clearance. I believe that my unfamiliarity with the airport led to this, and in the future I will ask for progressive taxi instructions unless absolutely certain.
