Sheila Mimms lost custody of her 1996 Harley-Davidson FXDL Dyna Low Rider Monday, when a court ruled that the 38-year-old waitress is an unfit motorcycle mama. 'Ms. Mimms has shown that she is incapable of caring for a young cycle,' judge Leon Orem said. 'It is the recommendation of this court that the hog be taken into the custody of the state until it can be placed in the care of a more suitable mama.' Among the Mimms transgressions cited: infrequent filter replacement, negligent outdoor storage of the bike and inadequate theft-proofing measures.
