She had some recent reviews - said she was on some site called Boston International but I can't find anything about it

There are a couple of ladies on that site that have worked with various agencies here in Chicago either currently, or in the past. It's not unusual for ladies to travel and work with other trusted agencies. So... Can't say I'm surprised to see her listed for an agency in another city. Just hope she comes back at some point.

Boston site not working.  If anyone knows where Maggie BB is let me know.
