Narrative:

After a smooth landing and slight rollout; my plane; for unknown reason; began weaving left and right to the point of exiting the runway to the left and into the mud. After the plane came to a stop; engine still running; I requested permission from the tower to taxi out of the mud. I was able to taxi about 50 yards until I got stuck in much deeper mud. FBO personnel pulled the plane out of the mud and to the maintenance hangar. Callback conversation with reporter revealed the following information: the reporter stated that at the time of the event the weather was windy; cold and the runway was wet. Although he does not remember the tower reported winds; he was told later that there was crosswind. He has never had a problem with this aircraft before and so guesses that he failed to control the aircraft in a crosswind situation.
