I have been doing quiet a bit of research about open carry in Maine and had several questions. Number one,Is there any age restrictions, I read this and it says no Statutory limit, I have asked several gun dealers and even the police and they can not define. Second, I know you can not open carry loaded in a vehicle, MY Father and I farm in the summer and drive our tractors several miles to various fields. We would like to open carry but would we have to unload when driving the tractor on road and infield, Just on road, Or not at all. Thanks for the Help.
