First just to be clear, nothing I said or am saying is based on personal knowledge: I was merely in the right place at the right time for someone to vent.
I had no idea who was running the ATC nor that she was leaving, so I was more than a little surprised that "where can I get a hamburger?" turned into 20 minutes of the recent situation with the ATC.
My first impression of what I heard was that while a likeable sort, Dixon was not exactly "one of us"(something that Marra DOES seem to be).
Second, after time, apparently Dixon's path of new initiatives and programs left the board feeling too little was being done with the 32 organizations who do the brunt of the on trail work. I volunteered that seemed to me to be both the most important and difficult part of running the ATC- it has to be difficult to tell volunteers what to do, its not like dealing with employees. I did not get much feed back on that, mostly more about how Dixon had a different vision. Given Marra's history with the ATC, I'm sure things are headed back to the way they were before Dixon. So while "pushed out" may be a bit of an over statement(or not), its easy to see why Dixon would choose to leave rather than fight for her "vision".
