Narrative:

At dekalb peachtree airport, GA, I was given departure taxi clearance 'taxi to runway 2R, hold short of runway 2L....' I began taxiing from FBO on the taxiway in front of the control tower (taxiway B) and instead of making the half right to pick up taxiway a, I missed the half right and continued straight ahead on taxiway B. I should have been approaching the intersection of runways 9/27, which were closed, but I was mistakenly approaching runway 2L. As I recognized what was happening, I began to stop and the ground controller called and said 'hold your position' which I had done and acknowledged. The ground controller then instructed me to taxi south on runway 2L to the first taxiway to the right, taxiway C, take it to taxiway a, and to continue taxiing on taxi a to the end of runway 2L, hold short of runway 2L and monitor tower. My aircraft was past the midfield hold short line for runway 2L on taxiway B, but had not entered the runway when I stopped because it didn't look right. In this area, txwys and ramp run together and are not easy to figure out. As I was taxiing out, the controller was communicating with another aircraft was perhaps distraction by that aircraft as I passed just below and in front of the tower. I was distraction by a blimp which was approaching the pdk airspace from the east, and by my passenger sitting in the copilot seat who was making several observations about the blimp's nose down attitude, and about the air conditioning system which was not providing cool-enough air to the cabin to suit him. There was no arriving or departing traffic on runway 2L when this event occurred. However, it was an active runway. I was mistaken about my exact position on the airport and that is the reason for this report.
