Now that we have the penal code for these alleged crimes, we would need to further research the case law. Interpretations made by the court as to what these laws actually mean. I believe that just being naked is not considered "lewd". In addition, clothing optional has been customary for over 30 years.
However, there is a danger here. Counties have the power to pass ordinances concerning such issues. I remember such a case was occurring in Huntington Beach, CA.
So, lets stay away from the county and probably the BLM and just work with the Forest Service with this issue. The Forest Service and Brad Burns appear to be our strongest ally on this issue. I think we should pursue having the area designated as clothing optional through the Forest Service.
