NANTICOKE, Pa. – A helmet would be good, but police said clothes would be a nice start when riding a motorcycle.

A local dentist pleaded guilty to disorderly conduct for driving a motorcycle with a naked woman on the back. The woman faces more serious charges.

Dr. Joseph P. Gronka, 39, was pulled over June 12 when police noticed Lisa Drozdowski, 39, riding naked on the back of his motorcycle. Since then, Gronka has paid $277.50 in court costs and fines.

Gronka declined comment. Police said Drozdowski was belligerent when she was taken into custody and threw a small pipe into her cell toilet, then kicked an officer who tried to prevent her from flushing the toilet. She was charged with aggravated assault, simple assault, tampering with evidence, resisting arrest and open lewdness.
