Narrative:

I was finished with my maintenance run at the runup area. My avionics man called ground. I was thinking of what I needed to complete as far as problems the aircraft had, instead of keeping the task at hand in my mind. I immediately thought I had clearance to runway 35R which was across the field. As I was entering runway 35L, ground radioed back 'hold short runway 35L,' but I was on the runway. Ground radioed, 'proceed without delay across runway 35L and runway 32.' I cleared runways and a military F18 made a go around about 300 ft AGL. Ground radioed me to call them. I called them, gave them some information they wanted on the ground telephone, said there was no problem with separation.
