hey, i do know a forum user who has been trying to get something cookin' there in tuson but nothing is organized yet.  i think putting up a note in the local organizing forums would be a great way to potentially reach folks.  seems a lot of people like me don't always look at the front site blogs.  if you want support in getting stuff going on you can reach other organizers around the country with local groups or email me supportATtheicarusprojectDOTnet
