I'm not aware of any advocacy groups in Wyoming, either. And even the big ones (in Chicago and Las Vegas) like SWOP, really doesn't offer that much hands on help.
They're supportive but if you're friend is being held on a $5,000 bond (YIKES!), I would suggest that she get some type of attorney to get her out of there.
(Note to Elisabeth: Don't go to Wyoming!)
Where in Wyoming did this happen?
