I don't think there is a need to thank anybody. You've become involved, and now you're just part of the big picture of OCing in Michigan, same as the rest of us.
But as a side note, yes, the information is crucial. I have stated over and over that I suggest against OCing unless someone is extremely confident with the law. Anytime anyone goes somewhere OCing, it is best to first ask yourself if it will for sure be legal, and if you are ready for something bad to happen, such as an extremely unlikely gun grab, or an unlikely but possible negative police encounter. Without extreme confidence, I suggest against OCing.
