No, the first post says it's legal for someone over 21 to carry concealed in their car. The second post says it must be in plain view or in a glove compartment (or like) only. So you could NOT carry concealed. They are different on that point (which is a pretty big one IMO).
Glove compartment would be concealed to me (long rifle won't fit, lol). So, the first statement would be correct as well. That's how I see it. Pretty much, it sounds like you can carry in your car openly, or in the glove compartment. I don't think it's too difficult to grasp, but I might be wrong.
