FiM off-seasen Events

[Zebra_Fact_Man]

I've seen similar threads for other regions, but I have yet to find one for Michigan. What are the 2012 off-season Events in the great lakes state and their corresponding dates? So far I have:

M.A.R.C. Robotics Competition 6/22-23
West Michigan Robotics Invitational 10/20

Kettering usually does one, i.e. Kettering Kickoff, but as far as I know their website has not updated yet so the 2012 details have not been released. I know there are others, but which ones am I still missing? Ohio and Indiana can also hop on this thread too if they want to.
