Posed nude in an urban setting

Been posing on and off on an amateur basis for a few years now, but today was something different for me.  I am in Southern California ... linked up with an amateur photographer who works in graphic design.  He wants to get more into photography.  Anyway, the location was Long Beach which is a fairly large city in Los Angeles County.  We drove around looking for various industrial area.  We found several where I felt OK about being nude ... He would get me in position then I would pull off my shorts and let him do his thing, it was great.  I did get caught by two women who were walking along a wash, but I chose not to react to them, and they just walked on by ... I am sure I have been the subject of the conversation for a good part of the day though.
We did this for four (4) hours ... it felt great.  He now wants to get a younger guy to pose with me ... he has some interesting ideas.
Just wanted to share the experience with you.
