Legally you can't conceal a pistol in a bar (defined as a place that makes a majority of its income by the sale of alcohol by the glass). But you can legally open carry a pistol into a bar if you have your CPL. I've done it plenty of times when I've stop in to have a burger or something. rsvectordude if that scares you then I guess you need to stay home.
To those that fear citizens legally carrying firearms (whether on a snowmobile or not) you need to do some research and learn the facts about the subject. There are hundreds of thousands of CPL holders nationwide that are out there carrying everyday. CPL holders in Michigan have to undergo training, background checks, expensive licensing process, etc so they aren't the ones you need to worry about. Personally I'm more worried about a meteorite striking me that I am about a CPL holder committing a crime against me. I carry whenever possible not because I am always scared of something, but because I CAN, "to keep and bear arms..." says nothing in the 2nd amendment about "except while on a snowmobile" or "except when some some people on an internet forum think its a bad idea"
"A right not exercised is a right lost"
Edit: I agree with jonesin that some of you seem to think that CPL holders are going to use their firearms to settle an argument, which is completely bogus. Only time its going to get used is when mine or my families life is threatened.
