Frankly, "open and gross" conduct is common among males.

Attleboro, Mass. (AP)
  Mr. Robert Bailey has be given a one year probation for washing his truck in the nude.  The 65 year old Mr. Bailey had apparently decided to not get his clothes wet at the local public car wash and shed them.  A woman vacuming her car called police. Mr. Bailey was found guilty of "open and gross" conduct. An interesting crime to be charged with. Most teenage boys probably violate this law too. Poor Mr. Bailey also has to register as a sex offender. Seems a bit much.  I suspect the judge was a woman.
Protect your washing,
