First thing is we need to VOTE pro-gun representatives into office, as well as a pro-gun governor.
Once they are in place, we need to call/write/email them letting them know that we want the laws changed.
I agree with you, many states have much more relaxed laws than what Michigan has.
I know in Colorado, in addition to open carry, you can carry open or concealed in a car without a permit, as well as concealed when you're hunting. Rifles/shotguns may be carried anywhere in a car as long as there is no round in the CHAMBER. There's no purchase permit, or registration of any kind.
