You guys are all havin' fun with this, but I get to deal with this situation nearly every week.
I live in S.E. PA very near to the borders of MD & DE, I am legal in PA & DE, when I carry, but it is virtually impossible to get a CC permit in MD.
My mother is in a nursing home in MD and my father spends the summers on the Chesapeake bay. When visiting either of them, which I do frequently, I always carry a lock-blade knife and have a large Maglite in every vehicle.
As you can imagine the MD constabulary frown upon any transgression of the state's "no carry" policies and vehemently enforce these laws. Any violation is a felony offense and not helpful in any way, whatsoever!
