Paying for Volunteering

Paying for Volunteering.  It seems wrong to me.  I'm giving up time and effort for a cause.  At this point, I think I'm just evolving in my volunteering.  I love helping with all of these events but I do have to draw the line at paying to do it.  It would be a different story if I am a fan of the event purpose/cause/theme. Otherwise if I'm just dipping my toes, not so much. I'll do my best to differentiate.  The one's on my page are free to volunteer for, with the exception of Burning Man.
