Narrative:

I was busy with my eyes inside the cockpit fine-tuning RPM and such. I looked up to see the PA28 on a collision course. I initiated a turning climb to the left, away from his turn. I believe neither of us saw the other until he was already turning, so the wing of the cherokee may have obscured me, thus keeping him from taking evasive actions. His turn may have caused the sun to reflect off of him and get my attention in the first place.
