Narrative:

As I turned left off of the runway onto the taxiway, after completing a full flap landing, I felt the airplane skip/hop to the right a little. I stopped, called ground to continue to taxi to the fuel pits. I was cleared and resumed normal taxi operations. After 800' or so, I felt the airplane gear moving and heard the gear warning horn sound. I looked around and visly and physically made sure the gear switch was in the down position. The aircraft settled on its nose and right wing and came to a stop. The gear indicators showed down and locked, with the mechanical linkage triangle and green down light lit. The left main gear remained extended.
